It's because people of diverse backgrounds need diversity in their community/social life as well. In Texas you have two kinds of diversity: white and Hispanic.
uffi... where to start?
Maybe you exhibit prejudice and ignorance of your own?
Did you know that, for example, Dallas has one of the largest gay communities in the USA?
I'm sure Texas could use more diversity, and I won't try to convince you otherwise since your mind appears quite made up, but your comment adds negative value to the conversation.
So I guess everything is just a matter of perspective once you start overgeneralizing.
Also, what's the problem with Hispanics? Wrong kind of heterogeneity? Honest question.
I think if you look at the demographics of Los Angeles and Dallas you'll find them shockingly similar:
% Hispanic: LA 47% DA 42%
% Non-Hispanic White: LA 29% DA 29%
% foreign-born: LA 39% DA 25%
% Black: LA 10% DA 25%
% Poverty: LA 19% DA 18%
