Just when I thought we were getting somewhere, sigh.
It's not Xenophobia to prefer to live with your own race.
Tell that to the people in the UK who have had there cities and town over taken completely.
"Xenophobia is the unreasoned fear of that which is perceived to be foreign or strange.[1][2] Xenophobia can manifest itself in many ways involving the relations and perceptions of an ingroup towards an outgroup, including a fear of losing identity, suspicion of its activities, aggression, and desire to eliminate its presence to secure a presumed purity"
Note I'm not saying racism, I'm sayingxenophobia and to me it's a valid call. white people moving out of an area because say brown people have moved in can often be linked to the above.
The fact that you're using terms like "ttaken over" kind of points to that.
Relations and perceptions of an in group towards and our group - check
Fear of losing identity - check
This of course isn't always the case but it certainly sometimes is. If someone is complaining they're being taken over by foreigners in a country like that is 80% white British and 85% white according to the 2011 census then I really think much ado is being made of nothing. Not to say there aren't issues in pockets, of course there are but nothing supports the theory the country is being taken over and people need to move overseas to be with their own kinD.
85% of the country is white, why complain about small pockets that immigrants of particular colours have congregated in? why is it a bad thinG?
