I've lived in the Southwest, never had a problem with language. Never. I've also lived in London, where you hear a dozen different languages being spoken every day. I also lived in Canada, multi-lingual, no problems at all. I currently work for a European company, multiple languages are spoken in our business meetings, no problem at all.

Common language is irrelevant. None what you list is actually a problem, you just don't like people who are different than you. At least you own it and don't deny that you just don't like browner people, I'll give you that.
