I don’t think very many people are celebrating his death, per say. More celebrating that with all the shenanigans and overzealous nature of that side, that they are NOT invulnerable to the rhetoric they, themselves are preaching.

Sorta like that cheer when you are watching a (very patient) cat being harassed by a lap-rat and the cat finally gives a nice swat, sending the dog running and crying to its owner.
