The poster was suggesting a hypothetical situation where that is a policy. Very few places in the US have 50/50 gender quotas, and I doubt any have quotas which include non-binary people. I believe they were mocking the idea.
I was not mocking the idea, but giving an example where a reasonable quota led to bad outcomes. While I’m against outcome quotas, I’m firmly against discrimination (including mocking) of people based on who they are.
So, this system is used in the United States, right?
