It's hilarious because for 4 years Trump (all his life, really) was (and still is) a complete vulgar, childish, lying, narcissistic a-hole. And republicans didn't say boo about it.
Perhaps if Reps would have tried to find common ground and stop Trumps name calling, etc. the Dems wouldn't be icing up the champagne.
But Reps wouldn't do it 'cuz their base was fine with it. So maybe your plea, noble as it is, would have been better expressed 4 years ago.
