Biden and his puppeteers spent their entire term trying to dismantle, destroy and desecrate everything Trump did, stood for and existed as. They tried to jail him, blamed him for every evil in existence, and used him as the scapegoat for every failing they had.

Anyone's feelings on Trump's actions aside, that was disrespect on a primal level. This is downright tame compared to what they did, and he has every right as a grown man to return the favor to Biden and Obama.
