Don't get Tex started. As far as he is concerned, the only true US citizens were conceived and born in Texas.
Being a native-born Texan may be more significant than being considered an American by birth, at least in Texas.
Growing up, all my schools were named for heros of the Texas Revolution: Stephen F. Austin, Ben Milam and others.
We didn't study any world history, or American history until near the end of the 8th grade.
Believe me, I understand exactly how Tex feels.
