I hope not - I am not a Muslim but my parents and other people I care about are. And even if that wasn't the case, I wouldn't want that to happen to any group.
I don't think that anything really bad will happen in the UK, but some of the other EU countries worry me with the kind of people they are electing into power.
Julius Streitcher (a war criminal) used to quote the Torah and the Talmud to "prove" that Jews were evil, scheming, untrustworthy and had contempt for all nonbelievers. The far-right are doing the same to Muslims.
Typical that no one mentions the slaughter of 1 million Armenian Christians at the hands of Muslims.
Worst case would be mass deportations.
If it were the other way around, and Westerners immigrated en masse to Islamic countries? Yes, then it would be a holocaust.
I doubt that we'll see anything quite so dramatic however i do suspect that these migrants will at some point arrive at the border of a country that does not want them and then somebody will overreact and shoot some of them.
I think Germany would rather allow all the inhabitants to be killed or converted to Islam than rise up against it. There's too much guilt over the Holocaust there, and they would rather pay what they see as the karmic price.
However, I suspect that if the situation is not brought under control, there may be a situation like that in much of continental Europe. If Britain manages to remain stable and control immigration so that things don't get quite so out of hand, it may end up being the safest place for the few refugees and immigrants that do get in. But there aren't the resources for an unconditional and unlimited acceptance in the name of compassion like what Germany did. That has to be kept in mind.
Probably and it's completely ludicrous how people don't learn their lesson, especially after the atrocoties of not even 100 years ago.
