“Is it harmful to ask what harm they are talking about?”
His “crime” is that he hurt their feelings. That is it!
Did he even hurt their feelings? He has an odd, maybe crazy conspiracy theory about how and why the massacre occurred. He did not insult the victims or the families of the victims. He did not implicate them of anything. They simply don’t like his ideas and want compensation for disagreeing with their politics. And a little blood money doesn’t hurt either. Leftists are known for caring less about their own children than their politics and their greed.
