First off, I haven't seen nor heard of any "Christians" beheading someone because they don't believe as Christians do nor have I heard of any "Christians" hanging gays or lesbians. While there may be some "Christians" who don't agree with homosexuality, opinions are allowed in a free society. Are you saying that just because the attackers were Muslims/immigrants, they're to be treated differently than if they were Christians, Jews, agnostic etc.? Why? Assault is assault no matter who commits the crime or are we to have a two-tiered system now BECAUSE they might be Muslims.
Secondly, the "no go" zones are not a right-wing anti-immigration invention - talk to the people, as I have, who actually live there and they'll tell you it's quite real so don't comment on something you know nothing about.
The fact that so many people have their heads in the sand is truly terrifying. I suppose that's how it was when the Nazi's came to power too.
First they came for the Socialists, and I did not speak out—
Because I was not a Socialist.
Then they came for the Trade Unionists, and I did not speak out—
Because I was not a Trade Unionist.
Then they came for the Jews, and I did not speak out—
Because I was not a Jew.
Then they came for me—and there was no one left to speak for me.
