If by open minded we mean writing off 26 million people because they live in a geographical area that's different than yours (and perhaps hold religious views, "quelle horreur!"). But what you really mean by "open minded" is "votes for Democratic politicians". And lucky for you, Dallas (just like all of those other bastions of conservativism, San Antonio and Houston) has a mayor who is a member of the Democratic party!
Funny, huh, stereotypes aren't always accurate.
