It's simple: people are afraid of being called racists/sexists/transphobics/*ists for opposing something that "technically" protects minorities. Can't blame them, because unless you are an edgy fuck from this place, I doubt you would like to do something to be able to hurt somebody. They don't seem to realize this isn't only being used to protect minorities, though, but to actively policy development with stupid decisions.
Some people around here have decided that the best way to fight back is by being an edgy fuck around their channels and triggering everybody around there, in hopes they get so triggered they an hero or something, but that's unlikely. This is not what you do to solve a situation, since you are just making them think those rules are necessary to protect them from the evil meanie hatechan trolls. Instead, you gotta win them at their own game.
Make a new GitHub account. Do nothing other than "being there", or in other words, make sure the community knows you exist, but actually do nothing of value. This can be achieved through commenting on pull requests or issues while avoiding submitting them yourself (yeah, not even pronoun changes. Those are considered useful by those fucks). Stay around, talk to people, and make sure they understand how oppressed your transexual ass (easiest one to pull, but you can also try to say you are an actual woman, or a Jew, or whatever) is, but otherwise don't be conflictive. Once they have started to recognized you, start fucking shit up: "your use of the word 'users' is offensive to me because it invisibilizes the transexual struggle, so change it for 'users of all genders', and no, don't even try to argue because you don't know how being transexual feels", "I feel we should change the name of the project to something else, since the word 'rusty' is being started to use by some alt-right collectives to talk about us transexuals, and it hurts my feelings", "I am offended by the use of 'his' in reference to Plato in this example of the documentation; we don't know if he really self-identified as a man", reacting negatively to any challenge other members may impose as if it was a personal attack, etc. If they try arguing, shut them down and force them to apologize (the CoC actually defines this as the correct procedure to follow), and repeat until they either listen to you or start ignoring you. If you ever get ignored, it would be a good idea to write a lengthy rant on how they are transphobic and how Rust is doomed to fail with such a shitty CoC that's so unwelcoming to extremely valuable members of the community such as yourself. Drop that identity, rinse and repeat.
The only way to make people realize something is shit is by poking at its holes until people get mad enough to actually change it. You don't get that by reinforcing the idea that such a thing is necessary, but actually the opposite.
tl;dr be a shit cunt, bring up the CoC whenever they argue against you and watch shit burn. The only way to mindbreak SJW is to remember them to check their privilege and how, according to someone much more oppressed than them, are doing social justice wrong.
If you want to watch a shit project crash and burn in no time, do this on Terasology, a Java Minecraft clone. Their CoC is so Orwellian you can call them "stupid cis-sexual crackas" without a reason and they should shut up and agree with it
