Stop playing into their reactionary statements. At least be neutral if you're not ready to call them out.
Make yourself comfortable with cutting them out of your life.
If you want to give them the opportunity to behave better around you, you can directly disagree with them by sharing your true opinion when something like this comes up. Those who don't suck will agree with you. Those who value your friendship over their own reactionary positions will at least try to respect you and stop saying things like that around you. If you get dogpiled, I'd ghost them.
If losing this group of people would seriously harm you, like severe psychological trauma, then of course do it at your own pace and maybe with another group of people lined up first. But otherwise you should plan on removing several them from your life because they're saying Nazi shit and you shouldn't support fash.
In terms of your title question, you should educate yourself and join a half-decent org. Given your current situation, I recommend being careful about what org you pick, as you don't want your first org to also be your primary friend group that you have to leave behind again, as you may politically develop in another direction and then be back in this same position but with the Western Leftist version, e.g. DSA Russophobes/Sinophobes or certain categories of ultras. Feel free to focus on your own education before joining an org, just remember that this is the trajectory!
