POINT OF ORDER
POTUS DOES NOT HAVE TO BOW TO ANYONE!
He is a "Head of State". Heads of State are not expected to bow.
This is where the psychological mind-fuk of what MSM does becomes so clear; because #44 did it and it was so publicized, now folks expect it. This IS NOT protocol!
Our Millennial fledglings think it's a deviation because they simply don't know anything other than #44 bowing to anyone he could.
The British loyalists have also been brainwashed in to believing their Queen is the world's darling that deserves this 'courtesy' from every living thing.
The Queen and POTUS are of equal rank (in theory- she is low-life child murdering scum in reality and deserves nothing but to bow her head at the gallows). Bowing is an Obama thing. More reason why our POTUS did not bow; good concedes nothing to evil.
Heads of State DO NOT BOW.
