People working on an open-source language aren't 19-year-olds on twitter, you're using the wrong heuristic here. They're there mostly to talk programming and work on a project together. The CoC is pretty standard language that you'd find at most conferences you attend. It specifically enumerates bigoted actions because several contributors are members of the LGBT community. The last thing many of them want is to deal with culture war nonsense seeping into their fun hobby.

I am honestly a bit confused because this whole comment chain looks like someone is starting culture war and drama? But you mean that the people who use gleam tend to be into culture wars, not the OP poster in the chain?

I'm gonna be honest, based on this thread it sounds more like the CoC is repelling people that are really into culture wars and internet drama.
