Notes:

My source is only a reply because KawaiiartsMr went on protected mode so one can't really see what his responses are. The guy that brings up the incels however still has his tweets up, and their as bad as one could expect when his use of "take it easy, it's just a drawing" in response to a drawing of 9 year old is followed up by "dark humor."
