Starting a psyop on 4chan for making edgy school shooter wannabes start aiming at billionaires instead.
"You see anon, it's not that girls don't like you or that your class has 1 non-white person in cornbread America, it's that billionaires are leeches in society, and the cops they own would stop you. Don't fire at classmates, fire at the upper class."
For good measure point out that people migrating into the country are often because the 1% are offering them otherwise high paying jobs at below minimum wage, but thanks to the exchange rate that's like a million dollars an hour back in their home country.
Don't make it obvious that you're on the Left or they'll ignore you on principle. Make it sound like you're "one of them"
I did it once, in person, and all it took was food every day for a few months. We all shared our food at lunch instead of keeping it to ourselves, and we all went away more full than we had before. (the reason is that we all got a larger variety of flavors than before, but that's not the point. The point is communism) Never out had to talk about leftism or politics either, people just sort of came around via eating.
