Why do Texans act like non-Texans are somehow "lesser Americans" when their state is the most un-American?

I've had enough with seeing these "American by birth; Texan by the grace of God" stickers. Many Texans I've met seem to have a superiority complex towards people from other states, thinking of them as being lesser Americans. The truth is that the history of Texas is the most un-American of all: a bunch of Americans moved to Texas, then under the control of Mexico still, and renounced their US citizenship in order to get Mexican citizenship so they could live and work there. They then broke free from Mexico and existed as an independent republic until the US had to come in and annex them cause they couldn't make it on their own. In other words, the Republic of Texas was a nation founded by traitors both to the US and to Mexico, and then they proceeded to seceed from the union less than two decades later. How much more un-American can your history be?
I do know about Texas and Texas; I lived there.
Sorry, I meant to say "Texas and Texans".

It's a religion and Texas is the church. It's another country and we are just colonies. It doesn't owe allegiance to any other country, unless that country is in the Mid-West and then it's more a treaty. Any 'foreigner' is legally and technically considered a cow or oil. You have to be a Texan protestant, the rest are only sects and unscriptural. NY is hell and the people there are pagans. Given all that, is it any wonder that they're suspicious of us? Wouldn't you be? Oh, yeh, and do you have boots and a hat in deference, answer me that? Or do you wear 'slippers' and go about hatless? Tough questions.
