"debate me" kids are another stereotype on the internet though. The idea that ideas should be entertained and discussed for the sake of it and come without implications attached is just another form of edgyness. It's another thing that often goes away with age or with touching grass. I know because I was one of them. Now I understand that the fact itself of discussing something publicly has moral implications.
Larping as a tankie is definitely a thing of immature, terminally online kids, but I wouldn't throw Lenin in the bunch. While Stalin is mostly condemned as a reactionary psychopath by pretty much everybody except a few leftist basement-dwellers, Lenin is still read and taught throughout the world. Nothing edgy in reading Lenin.
Edgy kids on the internet worship other psychopaths like Pol Pot or Hoxha.
