It makes me sad that people are so sensitive that reading a message like the one ESR wrote drives them away from participating in projects and communities that otherwise would interest them. At least this seems to be the narrative of the "PC supporters" here.

The world is full of assholes. I think it's better to get used to it than to shelter yourself, try to make every space safe or withdraw from interacting with other people.

I know I'm biased though. I am pretty thick-skinned so it's hard to see it from the other perspective.
