Texas History?

Okay, so I'm on this listserv, and everyone is complaining about how we teach Texas history here. I don't get it. When I was in school we were required to take 3 history courses. World, US, and Texas. Sure teaching a whole course on state history might be alot in some states, but Texas went through alot to become Texas the state. It's not like we're ONLY teaching Texas history. We just teach it too. What's the big deal? My mom grew up in Virginia and she had to take Virginia history, nobody's bitching about that? I think it's just because of the stigma attatched with Texas.
