Unpack what you mean by self-censorship exactly?

I regularly see people make frank comments about sexuality. There's maybe 4-5 people whose comments would be considered offensive in liberal circles. Many more people whose comments would at at least somewhat offputting. Whenever the subject comes up (no matter who brings it up, and which political stripes they wear), it often explodes into a giant thread of comments that's far more popular than whatever the original thread was ostensibly about.

I sometimes avoid making sex related comments until after the thread has exploded, because most people have already made the same points already, they're just repeating themselves because talking about pet political issues is fun. (When I do end up posting in them, it's almost always because my own tribal affiliations are wrankled and my brain thinks that engaging with strangers on the internet is an affective use of my time. I'm keenly aware as I write this that my justifications for engaging with you are basically meaningless and I'm just getting some cognitive cotton candy). Am I self-censoring in a way you consider wrong?

I've seen numerous non-gender political threads get downvoted with a comment like "politics is the mindkiller" and then fade away quietly. My impression is that gender threads (even if downvoted) end up getting discussed in detail. People don't self censor, which includes both criticism of ideas people disagree with and/or are offended by.

What exactly would you like to change?
