[dude with glasses in a communist t-shirt, arguing] I'm the only leftist here, your opinions are TRASH
[dude holding a theory book on smug, arguing] Read theory you losers, you're all WRONG
[dude in an anarchist hoodie, arguing] Nuh-uh, I'm the only leftist here, you're SHITLIBS
[the three dudes are now caught in a cartoon fight, glasses gone flying, punches everywhere, while a firing squad of nazis are targeting them with rifles]
[a confused nazi asks] Why… why are they still arguing?
It's shockingly easy to reach people of different political ideology if you view them as humans. Don't interact with the people who have punisher tattoos and roll coal, but that's not everyone right of center. Most conservatives are just ill-informed working people with no emotional intelligence or no capacity to care about larger problems than their next utility bill and resent progressive messaging because they're struggling so hard.
You can break through with class consciousness, almost every conservative I've talked to, and turned, started with educating them where their tax money goes, so get educated yourself how the tax code works, what the federal budget actually looks like, what your state's work laws are and such, and teach them why they can't afford food AND electricity some months.
You also need to be social and hospitable, do not have the intention of changing people, have the intention of teaching ONE thing and stick to it. This is what Bernie did for decades.
Edit: I will reemphasize for anyone reading down this far, PLEASE STOP TRYING TO CHANGE EVERYTHING. You're not going to get Bubba and Sheila down in the trailer by the scrapyard to suddenly start promoting trans rights and advocating for a free Tibet. Just let it go, our focus on micro-problems and social issues that don't impact the majority of people has been a deliberate sabotage of progressive movements to make people turn away. If we can turn people against Republican politics the rest falls in place and we get a better tomorrow, maybe not today but eventually and we have to start planting trees and stop expecting to have all our desires satisfied in our lifetimes.
