Earlier quoted context omitted.
The issue with such "free speech" instances not being the norm is that the instances which do allow "hate speech" are going to be clustered with unsavory individuals. If toleration is not encouraged at the core, it is a useless service because I don't want to spend my time in a safe-zone where I have to preface anything I say with "I don't mean to offend, but I think..." any more than I want to hang out with a group…
You could try not having half the things that come out of your mouth be easily construed as offensive, I guess? Seriously, I'm on mastodon.social and I've never once felt a need to preface anything like that.
Who is the gatekeeper for what is offensive and what is not? Why would you even accuse a stranger of having half the things coming out of their mouth being offensive?
If you haven't experienced the vitriolic "safe-space" syndrome present in modern heavily-moderated social networks, give it time and you certainly will. When, for example, I get reported and called a "future rapist" by a gang of radical feminists for stating that there should be legal consequences for false reports of rape / domestic violence, then there is a problem.
It was such occurrences that ultimately led to me leaving all social networks in the first place. The moderation is too heavy-handed and skewed in the direction of political correctedness to the point where if you disagree with someone you are labeled a nazi and silenced / blocked. It's a sad state of affairs.
