You referenced liberalism (Mamdani) as a goal for your future. What you're experiencing right now is all thanks to liberalism. You're not helping anyone by fighting for the status quo.
An easy start would be reading Blackshirts and Reds by Michael Parenti.
The Democrats are not your allies, unless you're an old, rich, white dude. Then they're your best bud.
Indoctrinating children is what the people you vote for do. You're clearly not as educated as you think you are.
Your goal seems to be making it peacefulish in the US so they can get back to terrorizing the rest of the world. Filthy liberal. As long as it's not in your streets it's fine.
Socialism isn't an unrealistic option, it's already been proven to work. The US has been fighting it for years. Many have died for the ruling class to stay at the top.
