There is a well known phenomenon typically associated with the Right.
Moral Panic
It happens on the Left too, as we are seeing. Members of the community are primed to react in prescribed ways to certain triggers, and spread the #MoralPanic to others they are networked with.
And no one wants to be the first to stop clapping. #Moderators are operating out of either ignorance or fear.
@EubieDrew sounds like an accurate description.
Just earlier someone said it was all justified because someone who said something antisemetic a week ago said a compliment to me and I said “thank you” (not knowing anything about their anti-semetic disposition)… which apparently makes it all justified… go figure
