He won't be deported. Brexit will have no impact on people like him who are already citizens
Precisely. These Americans fail to understand, that muslims - with support of both progressive left (which wanted to cripple nation states) and corporate right (interested in cheap labor) started to infest Europe already back in the 1960´.

Puts secularization and liberalism into new perspective, huh? It doesnt always work that great.
You need to look up your definition of the word "secularization". It does not mean that other religions get to impose their laws on you, it means that they get the same rights as everyone else: the law does not favor certain religions. A Muslim extremist talking about Sharia in a secular country, with no ability to impose his views on anybody else, has absolutely no distinction in the legal context from a white supremacist who wants to sterilize entire races of populations, but is unable to do so.
