What I said was meant to be taken in proper context.
The parent I was replying to was concerned about humans with perverse motivation working to aid a hostile AI takeover. Not as some sort of abstract thought experiment, but literally.
The statement you quoted was a means of countering that, in a literal sense. As in, "who would realistically do such a thing?"
When I was referring to the rationality cult, I did not mean the LessWrong community as a whole, but a small subset that fanatically applies the principles of rationality to their daily lives. Admittedly I could have worded it better.
Also, it was not my intent to imply said people were sociopaths.
