Couldn't find it either, and my experience with the gleam community is that they're very welcoming and positive people.

Agreed. Treat people well seemed to be the Gleam desire.

The counterarguments from the other party (seemed like one person with multiple accounts to me) were about their disbelief in trans people and the idea behind the Black Lives Matter movement (coupling it with some organization that copied the name and stole some donations)

I am on that thread as well. The issue with these "Codes of Conduct" isn't that they exist, it's that their purveyors force the "code" upon every participant regardless of forum.

If you don't support their special interests in completely unrelated venues, you are persona non grata and will either fall in line or be excommunicated.

I think you're seriously overreacting; you don't need to believe the same things that they do, all the CoC states is that if you want to engage with the community, you agree not to harass people. Every community has similar expectations; having it in a markdown just makes it more explicit.

Sure, you don't need to "believe" the same things they do, but if you are vocal about your ideals on Twitter, for instance, you are unwelcome.

"Don't publicly disagree with my ideals or I will use my little fiefdom to destroy you."

You might be letting your personal experiences pollute things. The CoC never says that. It's anti-harassment language, and specifically enumerates what that might look like. Some contributors are members of the LGBT community, and I'm sure don't want to debate their personal identity when they're there to contribute to a project and write code.
