I "partially" agree with you and nomerci, but I'd like to remind you of something the immigrants in the UK had encountered 30~40 years ago; signs of "No Irish, Jews, black or dog is allowed" were common in windows of houses to let and some clubs, so we can't say that 40 years ago things were better, turn back the wheel of time and live as a minority,perhaps you can come up with a different conclusion. I think the UK is better nowadays.
