That's the thing though, it's hard to ignore them since they pose themselves as coming from a morally righteous place, and they have the followers to back them up with their demands. Just look at the Opal thread I posted, it's started as a demand, and then a bunch of people who've had 0 to do with Opal start spamming the thread to back up the OP and hurling insults around at all the contributors for "daring" to associate themselves with one of the most prolific contributors to the project.
All of their arguments are also posed in a way to make anyone who disagrees seem like they're disagreeing with something very reasonable. It's phrased in such a way as to imply that they're in the 100% right, and if you dare disagree you're a bigot/homophone/transphobe/whatever other bad thing that can stick.
Every time I've seen a project get targeted by these CoCs, all the maintainers approach it from a good place assuming no malice, whereas the ones pushing for it will NOT take no for an answer.
I mean just look at one of the final comments in that locked Opal issue: https://github.com/opal/opal/issues/941#issuecomment-1132902...
They're blatantly trying to paint anyone disagreeing with them, no matter how mild the disagreement, as someone attacking them directly, and there's a scary amount of people who would side with them as well.
