I personally agree with this, from my limited experience. I would push back slightly though, and say they're a magnet for people with personality disorders, like sociopathy or more often just narcisism. Their character gives these people incredible validation and a lot of social capital. They also create an environment in which they're able to more effectively manipulate, exploit, and bully people.
That said, I love working at nonprofits.
Edit: I don't have any position on how this applies to recent event though. From my limited understanding of those, it's simply a difference of opinion.
