As may be, but their blood ran just as red as everyone else's when they shed it to create Texas. Texas wasn't created by a bunch of pissed-off white guys, you know.
Take a good look at the Goliad and Alamo butcher's bills. You'll see names like Buchanan, White, and McGregor. You will also see names like Esparza, Gonzales, and Perez. Think about it.
My comment wasn't intended to impugn anyone, it was just a joke. I know that Tejanos were and are vital to that Great State.
