About twenty years ago a friend of mine travelled with his wife in the South. He said that they were treated rudely because of their inter-racial marriage.
I'm glad that I'm colorblind enough that it took a minute for me to realize that his wife is Chinese and that this was a problem to them in their travels.
If I ever have an opportunity to relocate, such a thing will play an important part in my decision making.
The odd thing: those who were offended were Democrats, or Libertarians (I lived in Ron Paul’s district). Those who were accepting were Republicans.
The hard core neo=confederates there were Libertarian party. Yes, that surprised me too.
