The reason Texas is part of the USA is that Mexico made slavery illegal.

Remember the Alamo? A lot of white people don't know is that what the "brave" people in the Alamo were fighting for was slavery.

That's also why it took two years after the civil war ended for enforcement of anti-slavery in Texas. (it wasn't because of slow communication, as is told in revisionist histories, it was because white people willfully defied the law).

Freedom is always worth fighting for.
