As I see it, this is for one specific reason only: I don’t believe it’s the different cultural values from immigration that bothers them (they are literally moving into a wholly foreign culture; although I’m sure the Orthodox church gives some perverse appeal), but I believe they are bothered by ethnicity/skin colour.

So, because you don’t believe it, it cannot be true? Resembles the same small world view which Nazis have - sorry, I need to add to be in line with your words: I believe.
