A combination of events at Reddit and LGBTQ in Tech Slack spurred me into a tweet storm about online spaces:

The tragedy of all online community spaces is that the goals of "inclusive" and "safe" are, at the extreme, mutually exclusive goals.

If you keep including people you will eventually end up with people in the same space who cannot stand each other and will not get along.

At some point you have to exclude someone. You get to pick if it's the people feeling unsafe, or the people making them feel unsafe.

And *that's not always an obvious choice*. Somebody's "reasonable topic of discussion" is *always*, eventually, somebody's threat trigger.

I've run online communities for 20 years and I have learned that there is not even an approximation of a consensus of "reasonable".

This is why online communities fragment. Let them do it. It's the only viable solution to the existence of mutually incompatible people.

— Laurie Voss (@seldo) July 13, 2015

Define your space clearly. Let in anyone who shares your reality. Be honest that people who don't share it will be excluded. Say why.

Don't wring your hands about free speech. You are under no obligation to let people say things you hate. They can go elsewhere, and will.
