Go ahead, delete it if you don’t think it was a good comment,
It was an honest attempt to think of instances of paranoid uncertainty (protestors don’t know if other protestors are acting in good faith), but sure, delete it if you think it wasn’t up to standard,
In other groups with I’m familiar, you would kick out people you think are actually a danger (e.g. you discover the guy is a convicted child molester, and have some intelligence to the effect that they are not a reformed character) or you think they might do something that brings your group into disrepute. (I can think of one example where the counterintelligence investigation of a group member suggested that they were setting up a financial scam and were planning to abscond with people’s money).
But otherwise, I think it’s a sign of being a cult If you kick people for not going along with the group dogma.
