Why do Coloradoans not like Texans?

I don't understand why. I haven't said one bad thing about Colorado since i moved here a week ago, but the second i tell someone i'm from Texas, they don't like me. I understand that there are some Texans who have a little too much pride in our state, but that's not all of us. Most of the people i know from there are definately not like the stereotypical texans that you see on tv, and it's not our fault it's so hot. So why hate someone just because they're Texan? What did I do to you?
