They're a weapon of "social justice" - 90% of CoC rules are common-sense stuff that doesn't have to be said, combined with one or two "progressive" ideas shoehorned in.
I was once told I couldn’t present a calorie counting/diet app at an Elm conference because it violated their CoC about discrimination based on “body size”.
And "social justice" is often a weapon of capital interests in disguise.
Mate, thats just rules. rules you don't agree with.
