I've lived in Texas all my life, so I actually know this stuff.
Texas is pretty cool, things are generally bigger here, but since when is that better or worse? We are not all racist. In fact, most of us are some of the most tolerant people you'll meet (i.e. we are not all bible belters). That's just the super small towns where people aren't extremely educated. We are usually fairly friendly, unless someone else is rude first, and we will ALWAYS stand up for, and defend our own. We have lots of pride in our state, which sometimes makes other people mad, and/or pisses them off a bit.
Oh, and we don't ride horses to school or wear cowboy hats all over the place either. Maybe one in a thousand people actually wear boots, unless you're in rural texas, which is a completely different story.
We may be a bit obese, but hey, we like fried food. Lots of people do, we're just a little more enthusiastic about it here!
Texas is simply texas. If you don't live here, you don't know. Don't knock something until you've tried it! (or been there, in this case!)
