All of the folks I have known online from Texas have been good people, and I've only had one disagreement with any Texans online.
Years ago on a performance car forum, one young feller from Texas didn't like the fact that in my location, I referred to my home town as the oldest city in the U.S. He griped about it, and in response changed his location to something like "Texas: The Greatest State In The U.S."
I told him that the fact that St. Augustine was founded before any other city in the U.S. was verifiable, but his statement regarding the greatness of Texas was simply opinion and I told him that folks from the other 49 "greatest states" could legitimately object.
He started talking about the size of Texas, so naturally I compared Alaska to Texas and showed that Texas was decidedly lacking in the comparison. So, he then tried to put forth the statement that due to its status as a quasi-independent republic prior to its admission to the United States, Texas is the only state allowed to fly its state flag at the same height as the U.S. flag. I showed him that this is false, and that Texas is subject to the same rules as all other states regarding flag etiquette.
Don't get me wrong though...Texas is a great state, and you'd be hard pressed to find a state with a more diverse topography, or a more interesting history.
