It's not white countries, it's countries. For example, is Portugal or Spain a white country? Because they would for sure vote for less immigration.
And yes I'm also completely for very limited and controlled immigration. But that's not because I'm white...
You need to study more philosophy and history.
What you call white is a mix of things that people call the Western culture. Stuff connected to Ancient Greece, Christianity, etc, etc. That's what you actually like, not the fact that the people are white in skin.
Because there's plenty of shitty white trash people, disgusting and dumb.
