(If anyone knows about numbers along those lines, I'd love to hear about it.)
Stop trying to insert your identity politics into everything. Let's just leave a few pure things in this world, please.
Rust has had a code of conduct from the beginning too; that's their choice. Its also part of the Mozilla charter I believe.
If you don't like it, tough luck.
Run your own project however you like, but you've got no ground to stand on how others run theirs.
There is no moral obligation to have a diverse group, just to have a group that is tolerant of diversity, in the interest of fairness for members of minority groups. Encouraging actual diversity is just a strategy to avoid letting people who don't care about this stuff develop bubbles of intolerance in homogenous bubbles where intolerance isn't challenged regularly. The presence of diversity indicates a lack of intolerance, but a group consisting entirely of one demographic could be just as tolerant, and its homogeneity just a coincidence or a result of lack of advertising. So I find it a little strange when a group is "congratulated" on its diversity.
My post above was a super-passive expression of this.
Exactly this. The internet is the great equalizer. There is no need for anyone to know anything about me unless I choose to bring it up.
For a technical project, conducted and run over the internet, my work can stand entirely on its merits in a way that would not be possible in a regular office environment.
Does the color of my skin, my gender or my sexual orientation matter when providing feedback for a project such as this?
I would argue that those things are entirely irrelevant in this context, and wouldn't want them connected/associated with any contribution I made.
Put another way, your skin color, sexual orientation, gender, etc. likely will not change your contribution. But if it turns out that people of a particular skin color, sexual orientation, gender, etc. are somehow disincentivized from contributing, that's a problem.
