You then have to ask how they check other mods, and whether they just dismiss things that should raise red flags.
I think it's clear that in certain circles, being called out by "transphobes" is seen as a qualification. The "us" and "them" mentality is so rigid, that extreme accusations from "that" side prove you're "one of us".
This is kind of projected to what you see in reverse - wild accusations with no basis against people like Jesse Singal. They make those accusations knowing they're false, because he's not "one of us". Accusations of sexual deviancy are seen as just a power tool, never a real actual thing.
So if everyone interested in "safeguarding" is a "transphobe", and people even say things like "safeguarding is a TERF dogwhistle", then it's open season for all sorts.
