That's the marketplace of ideas, baby.

This comment feels a little conspiracy theory-ish.

If a sufficiently big block of customers likes the idea of 'minority, lgbt and women's rights as you put it, they you're gonna see a bunch of companies trying to present themselves in a way that if favorable to that block.

Very tangential. Those sorts of spaces do exist, and likewise pockets of racism, homophobia, transphobia, and misogeny all exist too. Hating cis white men for existing isn't something that should be acceptable, and death threats are never okay. And there are stressors that they do face - the suffering of others does not invalidate your own. But at the same time, there are also plenty of spaces mocking and belittling trans people, gay people, black people, and women in general. Those places also spam death threats, only these death threats are a little more credible, a little more real, because there is a history of real, physical violence against all those demographics. At the same time, there are many people who just genuinely don't understand, who were sheltered by the previous generation's willful ignorance, who phrase their questions in a way that looks, at first glance, like another unprompted malicious attack. The violence is why those communities react so strongly to those questions, and why they are so hostile to what is, by all accounts, a reasonable statement. In more closed off digital spaces, where conversation is focused around issues common to those demographics, like the violence or discrimination they've experienced, it might come across as uncaring - if a trans woman is talking about how a cute guy she was talking to at a bar stalked her and tried to beat her after she mentioned that she is trans, and someone chooses that moment to say that it's not okay to hate cis white men, it just comes across as intentionally uncaring, as if that person saw all of the murder, rape, violence, hatred, and discrimination these people experience in daily life, then decided, "Nope, your attitude towards white cis men is the real problem here". Open spaces often use the same heuristic to determine if someone is acting in good faith, but due to being open this tends to catch a lot of people who aren't familiar with the heuristic at play, and only see a perfectly legitimate statement that seems to put everyone in a frenzy. Now this isn't to say that these communities don't take it too far on their own. There are some which engage in doxxing, death threats, and all sorts of terrible behavior, but those communities are not the whole majority, just as the racist, transphobic, misogynistic and homophobic groups aren't the whole of cis white men. In both cases, those groups simply are the loudest.

Okay? Like I said, people are completely free to build sites that have the moderation preferences they want.

I don't really see how this relates to what I said
