[Non-Sequitur]

Texas came into the Union by TREATY. And that treaty gave rights that other states didn't have, and still exist today.

Nonsense. Half the territory of the United States was obtained by treaty. California and Vermont and Hawaii were all independent entities before joining with the U.S. Texas was admitted as a state, same as those three, and it has the same rights as every other state. No more and no less.

Example: Texas retained ALL of it's public lands. The Federal Government owns only what it purchased from Texas, such as Ft. Hood,etc.

So? So did Pennsylvania and New York and Virginia and all the other original states.

Wrong.

You had better check your sources.
Texas was it's own country from 1836 to 1845. Read the terms of the treaty.
