I've got three incredibly close and good friends. They aren't perfect people, ranging from typical American lib, to centrist/conservative. We generally stay away from hot button topics, because we just don't agree on stuff.
(ie : an argument that i made suggesting cops don't belong in kids showa/movies, and they were all cool with it because "what's the harm in showing kids what police should be)
I linked to a meme on Twitter just today, and the user had a hammer & sickle, after laughing one friend said" wow, hammer and sickle big yikes". They don't have any idea about where I lay politically, and frankly it's been a pretty radical shift left in the last 10 months.
Anyone else have a situation like this? And how do you approach things?
Yes, be a good example. Be a normal, likeable, approachable good friend and also be a communist. And also be a good communist and stand up for things you believe in and speak out against obviously harmful things. But mostly be approachable as someone who has set a god example and is knowledgeable about communism, as you will be proven right and reasonable people might come to you for genuine insight and guidance one day.
