The other key difference between Jimmy Kimmel and Donald Trump is that to my knowledge, Jimmy Kimmel did not insight violence. Nor did Jimmy Kimmel attempt a violent coup d'etat to stay in power in an elected, public office on January 6th. Nor did Jimmy Kimmel violet any oath of office to uphold the Constitution. Nor did Jimmy Kimmel attempt to appoint or support appointing fake Electors in a scheme to thwart the Electoral Count Act. Nor did Jimmy Kimmel encourage people to go to the US Capitol building to physically try and stop the electoral vote process from occurring.
Trump's attempts to insight violence and his attempts at a coup d'etat to stay in power were primary reasons he was canceled off of social media I do believe. I believe his bans on Facebook and Twitter came after January 6th's attempted insurrection and coup d'etat, did they not?
