Decorum forcing people to only say nice things about a piece of shit person because any criticism or expressing happiness that he is gone being misconstrued as supporting the way in which he died is bullshit though.

How you die does not redeem how you lived. You do not become a hero in your death when you were a weapon of the enemy in your life.

Pastor Howard-John Wesley on Charlie Kirk's death.

Never believe that [bigots] are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The [bigots] have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.

• Sartre on Anti-semites, but applicable to all forms of hateful oppressors.

IMO it's fully decorated to say "I was taught that if you don't have anything nice to say about someone, don't say anything. For that reason, I will not be talking about Charlie Kirk."
