Dude, you will just get banned if you say anything really controversial. I take and am grateful for what I get.
It's the same rules at work and in public. People are quite self-righteous, and their minds can seldom be changed.
You want to minimize the risk to yourself, while still having access to the resources and community when you need them the most.
Pay attention to the format others use. You can ask unique questions, so long as you are polite and professional. Don't ask anything NSFW, rude, deragotory, or political. Especially pay attention to mod and admin leanings. They will ban you, whether you are right or wrong.
Keep negative vents sparse, you generally want to be positive outside of doomer communities. People won't take you seriously if you are always negative.
This is the internet survival guide, as far as I can remember.
