Such a rant is 18 mos late. We are now in the stage of processing the pathologies and criminal acts.
It's never too late for vanity. That's what this is all about, the Deadly Sin of vanity, and noting could illustrate it better than this example. Oswalt uses the vaccine shots as a means of putting himself above those who have not chosen to have them, who he calls "backward, racist, sexist & etc." He associates the unvaccinated with all of the worst things one could be to the liberal mind. He raises himself even higher by claiming to be double boosted. His audience takes the opportunity to join in this feel-good vanity festival by cheering to affirm that they are not one of and better than those. Oswalt is a clown, not a comedian.
