I’d guess you have a different understanding of what danger is. “has a history of attacking children” and “will have a corrosive effect on morale” are both dangers, just of different things. Companies kick out people that seem to be introducing a danger of being net negative for financial reasons (very widely understood). A church will kick out someone who is a danger of leading others into sin. A well managed forum will ban someone who is a danger of making the experience worse for everyone else.
Nowhere does the OP say anything about kicking people out for not going along with the group dogma. There are multiple groups where that is treated as a real danger, but I don’t think that’s a fair criticism here? Unless you mean by dogma something about open discussion, truth seeking etc., in which case acting against them really is a danger which needs to be removed. A garden without a gardener won’t last long.
