Pretty much all of this is horsesh*t. Not that youd take the word of the LA police chief on ICE's actions to account, nor literally anyone you disagree with. This is just the world you WANT to live in, complete with ICE raiding elementary school graduations and deporting children who are US citizens, and if literally any community stands against this they'll automatically become "paid organized leftists" in your braindead world view.
Its hilarious that people like you will live somewhere that WAS Mexico, you've probably been surrounded by Mexicans and Mexican-Americans all your life despite your best efforts to change that, and you'll still rage about Mexican flags, something you've seen all your life. But yeah yeah, invasion and replacement something something.
