IMO, this smart-assed usurper and his administration are choosing to ignore protocol and just plain good manners and are snickering about it from their liberal, lofty perch of assumed superiority.
In other words, to paraphrase Forest Gump, "trash is as trash does."
‘_______their liberal, lofty perch of assumed superiority.’
I think that’s it - you’ve got it!
Otherwise, they’re not really ‘learning on the job,’ are they!
