Racially? Pretty fine. Our blacks tend to be Africans who came here to be educated or to work, secondgen and beyond all sound British and speak like Brits, and the firstgens are usually friendly enough.
East Asians integrate well enough though they're a bit reclusive and tend to keep to themselves.
T*rks tend to be decent enough, I think they adapt to Brit banter quite well. They're probably cunts in Germany because Germany's work obsessed humourless culture makes them uppity.
The worst troublemaking ethnics we get are South Asians, though not necessarily for racial reasons. No, the issue Britain faces is an ideologically/religious struggle rather than a racial one.
It's the disgusting face of radical Islam at the moment, but there's always been an ideological war. The Protestant/Catholic conflict that went on for a few centuries was the one we've been used to, often involving the Irish- but that's slowed down into a sort of peaceful or tolerant conclusion so it seems like Islam has come in to fill the religious hatred vacuum that the conflict left.
The belligerents in this struggle isn't really straightforward to see. On the one hand we've got the hardcore Islamic fundamentalists that preach hatred in the streets for an average Tuesday, and they tend to hate everyone that isn't them. They're opposed fiercely by the rising far right movements- some dubbing themselves anti-Islam. These movements seem to get merged with skinheads and neoNazis. Now, these groups are opposed fiercely by the general sensitive and emotional Brit population and left-leaning media, students, and a lot of women. The people who warn about the dangers of Islam often tend to make the bad mistake of saying "Muslims" instead of "Islam" which lefties get really annoyed about since "not all muslims!" and that's really their main argument, leading them to ignore the actual bad shit a large amount of radical Muslims do commit.
