It may also be how I phrased it, I still read HN and watch some YouTube and Instagram, from my phone just with quite strict time controls.
There are no powerhungry mods that'd ban you without an explanation, but you can still have a conversation without being called homophobic names. The hivemind exists, but the opposition is strong enough that even controversial voices can be heard as long as they are well-argumented.
I find the discourse on HN to be (usually) thought-provoking and largely respectful.
As in: knock yourself out, I don't need to get into internet fights about why I think your opinion is ridiculous/oversimplified/ill-informed. If I get a whiff that the person is not going to be reacting productively I just don't reply.
