I'm one of the most socially liberal people here, but just as a general societal question here in the US...
,,,when did all this hugging to greet each other start?
Johnny Carson used to greet male guests with a handshake, and any hugging of a male was done for comedic effect.
Jimmy Fallon practically puts on the clothes of his male guests, he hugs them so much...but it's not just him...it's seemingly everyone.
So, what started this? Black dudes doing it first and the rest followed because they set the "cool" culture here in the US?
I honestly have no idea and am looking for answers.
