start introducing them to your politics slowly. very few organizing tips include radicalizing your already existing circle of friends and acquaintances

Develop a good collection of quotes to start dropping. There's a communist quote for every occasion.

Become a Buddhist. Attachment is suffering.

I'm joking, but still, why does it matter what some people online think of your views?

I mean, are they reactionaries who are gonna want to murder you or something? If you're not in actual danger with your positions, you can let your positions show in context when the conversations come up. I remember a time with a situation a little something like that where the conversation was beating around the bush a bit with criticisms of how things are going and I mentioned capitalism directly as a problem and got straightforward agreement from someone who I had thought would be more liberal about it. Not to say this person was a commie, I doubt they were that far, but you really don't know sometimes until you poke. And people can change their views, albeit with time.

So though I wouldn't advise coming in hot with "Stalin did nothing wrong" type rhetoric unless you want to start a fight and thrive on that energy, you also don't need to act like your views are going to get you shot unless you have reason to believe it's actually that bad in a specific context.

Without any context, what advice could we really give?

Well, if you've been studying dialectical materialism and how to analyse things and events as processes that are related to, influence and are influenced by other processes, you can always share your thoughts on particular things. As in, you can share your politics and Marxist philosophy by correctly applying them and bringing some clarity to our current reality and demonstrating why certain things led to certain developments. This will surely get positive feedback. Well, unless there are some severely reactionary and irrational tendencies amongst your online friends.

I dont reccomend doing what the bassist for Les Razilles Denudes did. He was part of a revolutionary communist group that hijacked a plane in Japan and took it to North Korea before defecting amd living in NK for decades.

Although I belwive they didn't actually hurt anybody so maybe that is a suggestion, seek asylum in Cuba or the DPRK
