I'm not saying you're far-right because you're a racist xenophobe, that doesn't require someone to have a certain political standing, and anyway it's hard to not be hateful of immigrants when you only hear about them when shit goes down. This is what happens when unregulated immigration policy allows both "somewhat normal" immigrants and criminals along with other scum to freely enter a country under the name of "refugee". It's especially bad because of not compatible cultures and values (woman's position, certain behaviours and respect for law versus tribalism and looking after your own folk).
And your reasoning is flawed - saying that most prisoners are black therefore blacks didn't evolve to be civilized is like saying "80% of prisoners are male, therefore males haven't evolved past primitive hunting activities and aren't civilized", it's much more complicated than that.
