I think that Muslims must be concerned with the direction the EU is taking with regard to Islam and law making that affects Muslims. If the restrictions on practicing Islam becomes so much that Muslims would not be able to live in Britain or lose their identity; what does the open borders and easy emigration matters in comparison? In fact, Britain is probably one of the least xenophobic countries in the world. When deciding on the issue of who Muslims prefer to be making laws . Muslims believe in the Islamic principle of preferring the lesser evil when they have to make choice between two evils of different degree. A major factor for backing 'Remain' was the misplaced feeling many have that the EU are moderates and Britain's policy makers attack Islam. There is so little reality to this that it is hard to understand where people get the idea from. Many, many people, even some respected Muslim organisations, are still mixing up the European Court (and convention) of ''Human Rights'' with EU membership. The fact is, now Britain still consider it bound by the ECHR which is run by the Council of Europe, and even if Britain had remain the Britain could still abandon the ECHR as they are not linked. That being said, it is worth noting how little use the ECHR has been for Muslims in Europe. When France’s niqab ban was challenged it was thrown out as being “not discriminatory” because the ECHR judges pretended not to see past France’s transparent tactic of also banning balaclavas and other face coverings that no one wears. Britain still consider itself bound to the judgements and law making of the 'European Council and Court of Justice'. It is not an easy figure to calculate, but estimates are often that between 10% – 65% of new laws affecting the Britains are made in Europe by British Nationals did not elect and who they have almost no chance of challenging. Just a few weeks ago, the European Court confirmed that G4S in Belgium banning its Muslim staff from wearing the hijab was “not discriminatory”. It seems neither the ECHR nor the EU court have any interest in defending the needs of Muslims. In Britain, G4S confirmed that employees would not be affected by that decision. The lesson is that Britains’s Equality Act is better than than the EU judgements. Still, for some reason, many Muslims think that if their government brought in a law negatively affecting Muslims, EU judges would rise to their defense. In fact, it is the judges in Europe they should be worried about and the fact that British judges and politicians in Britain, even if every single one them was a Muslim, would probably still have no ability to change laws enacted EU wide . Laws that are actively being pursued around the EU are bans on the niqab (so far France, Belgium and Holland), hijab (many countries in various settings such as universities, schools, government jobs, plus the new EU ruling allowing all companies to ban them if their national laws allow it), halal slaughter (Denmark) and the circumcision of males (many countries in the EU have actively pursued banning it). It is vitally important to realize that despite legal challenges, within the EU there has been little or no help for Muslims over these blatantly discriminatory restrictions on their life. EU membership has done them no favours. If our sisters were forced to remove their clothes to go outside, if our boys were unable to be circumcised and if we were unable to eat meat ,life would be dramatically harmed for Muslims, some may say it would be impossible to live here. It is probable that the evidence points to it being much more likely to come from the EU rather than it happening in Britain first. And, if it did happen there first, I can see no evidence to point to any likelihood of help coming from the EU. Some ask that were they to leave the EU could the Britain not ban these things anyway. Of course it is possible, but the most important difference is that Muslims would have a chance of challenging it here, if it comes from the EU we would have no chance.
In Britain many tend to believe the level of xenophobia among the British people is quite high because we see it in isolation from comparisons to other countries. In fact, Britain is probably one of the least xenophobic countries in the world. If one have kept up with the rise of anti-Muslim group PEGIDA in Europe, he can compare their huge rallies in Germany to the far right efforts in Britain. Being called off in Liverpool because no one turned up;[http://www.independent.co.uk/news/uk/home-news/liverpool-fascist-march-cancelled-after-barely-anyone-turns-up-10457614.html] getting kicked out of Leicester,[http://indy100.independent.co.uk/article/britain-first-goes-back-to-leicester-gets-chased-out-of-town-again–WkeuyUkevmW] twice;[http://class-struggle-anarchism.tumblr.com/post/92918070059/britain-first-chased-out-of-stevenage-by-royal] Stevenage; Dublin,and London on a weekly basis.[ https://www.rt.com/uk/339141-britain-first-flee-london-mosque/] Fringe groups of hooligans persist but they are more than matched by the “Antifa” anti-fascist movement. By contrast, in Austria a few weeks ago, a far right candidate of a party with historical ties to Nazism was a percentage point away from being elected president. In Britain the idea that someone akin to the Britain First leader would get 50% of a general election vote is almost impossible but, across the EU, support for far right political candidates is increasing, not least for Members of the European Parliament. Very often, for how strongly they speak out against Islam and as mentioned above, these are the people would have decided British peoples laws in the near future. I do not want to completely downplay the xenophobia in Britain or overplay the situation in Europe but it is good to look at the comparison and reflect on the direction of travel. In the past and present, the popular support for these xenophobic types of movements around Europe points to an acceptance of their ideology by the common non Muslims and this is very important when it comes to guessing what politicians could do next in a democracy. At the very least, any politician in Britain who wants to legislate against Islam has to move more slowly here. When Theresa May announces a review of Sharia councils of course Muslims there felt victimized but they should also be aware that elsewhere in Europe they would more likely just go ahead and close them down without any consultation. On that issue, because many Muslims are from an immigrant background there is a tendency to defend the concept of immigration. However, it is not a very clear cut issue. It used to be the case that immigrants were sought from the commonwealth countries and, in fact, quite broadly from around the world to fill whatever needs arose in Britain. That changed when the EU so called free movement policy came into being, filling Britain up from only one part of the world and leaving no capacity (psychologically perhaps more than physically) to take immigration from the rest of the world. So still now Islamic preachers from around the world may very well enter Britain for the purpose of Da'wah .And I don't think there are much non British Islamic preachers from Europe .
I even do not see it as xenophobic to want a points based system to allow controlled immigration from the whole world rather than uncontrolled immigration from just one part of it
