Actually I can. That group of people acts as an enabling environment, making the behaviour seem less extreme to those associated in that group.

Do you seriously not have any moral qualms about lying about millions of people and claiming they target and intimidate people?

I don't see these "millions of people" actively working to make sure the person making those threats is found and brought to justice. Instead, I see lots of them going "yeah, that bad, but the other side did...." or "hey look, she was logged onto 8chan. She probably did it herself" or at best "We shouldn't say too much until we know who did it".

I'll condemn that behaviour all day (behind the safety of my throwaway account)
