I think they do that because they're hypocrite and want to appear loving, when in fact, they don't give a f**k.
Why don't they hug the beggars, the only people that need to be hugged? Or those who are in pain.
Their love isn't unconditional at all, but worse, it is pathetic. I feel disgusted when somebody wants to hug me for no reason.
It also seems snobbish - "if everybody does it, then I should do it too, even if it makes no sense".
