The following passage (borrowed from a twitter feed) is very suggestive:

I imagine there’s some value in people being able to say things without having to worry about being evaluated (which is what “racist” is). This is what rough drafts are for.
But rough drafts also serve another purpose: to elicit cheap criticism in a low-stakes environment. You can’t forget that part.
If you do, then you’re just talking and making other people listen. What’s the point of that?
