Political discussion can often end up in a shitshow that creates a huge moderation headache. I enjoy not having to worry about doing much moderation, but that's also resulted in a community that's not particularly active.
What are you getting out of this community? Would it be better to allow for overt political discussion?
Lemmy.ml is famously authoritarian, I dunno how you haven't gotten banned from the entire instance yet, you must have only pissed off a mod rather than admin.
Most other (non-tankie) places across the Threadiverse are pretty chill, just be respectful/polite to people as you argue your salient points and counterpoints and you'll be actively welcomed.
Of course the other side to that is that if you can't or won't stop yourself from causing agitation aka trolling then mods may have to stop you by banning you, choosing to protect their existing members over you - though the level of desired or even allowable level of contention varies greatly depending on the community, which is what this post is about. Just make sure to read the sidebar and you'll easily be able to tell which ones are which. e.g. Chapotraphouse@hexbear.net loves a good fight, though that instance has been defederated from discuss.online so you'd need a different account to participate, perhaps one on hexbear.net itself.
I started checking the sidebar of every instance that isn't discuss.online (the instance I use), and their rules too. If I see any signs of a so-called Code of Conduct, I know there are some issues. I placed that link to a Mastodon post on it, and I hadn't seen what had happened yet.
