It's not the 99 times when your parachute opens that you stress about. It's the other 1%.
(Mis)interpretation reduces to choice, as does the principle of charity. With a large enough audience fallout is a statistical certainty.
Arguably the (male) head of the Free Software movement has no place debating the definition of "sexual assault" or "statutory rape" in a conversation about a human trafficker and child abuser. His opinions there have zero value (not to mention that a debate over such definitions is missing the point entirely), and engaging in that conversation -- even to come to the defense of his tangentially-related dead friend -- was a very poor choice, even for someone known to be contentious and often misunderstood.
And they could self-organize into self-selected groups. Then each type could best thrive in their own self-constructed communities.
And they could practice other-tolerance for the other sort of folks. Because tolerance.
Not only getting one's point across better, but actually getting a better point across.
On the whole, definitely a net positive.
I've found that a net good thing at least for myself. I used to be the dude who would blurt out whatever popped into my head and not care too much how it would be received by my audience, and sometimes even relish the fact that it was badly received.
By self-censoring and thinking through what I'm about to say and thinking about my audience before I open my mouth I find not only are social interactions easier and more pleasant, but I actually get my points across more consistently and clearly. People are then also more open to listening and don't always automatically get defensive. So ironically applying self-censorship has made it easier to make the points I actually want to make.
