Yes, this is clearly an issue of individual-level evil rather than the inevitable result of a toxic environment that piles on anyone who disagrees and treats charismatic ideologues like gods.
Speaking of Rationalism, it’s no wonder a group which demands exploitable memetic backdoors has had attackers “guess the teacher’s password” (to use Yudkowsky language).
All of this “if you’re X race/sex, you must shut up and listen and not argue” is a pattern for compromising memetic defenses against being subverted, and arguing with it is not very #woke, so you’ve got a flock of the metaphorically immunocompromised just waiting to be preyed on.
It’s a rootkit for your mind.
