Nobody should force a hug or a kiss on anyone. As I replied to another commenter on here, as soon as he waved me off I dropped it and did not make an issue out of it. I respect your boundaries. If you don't want to be hugged, kissed, or touched that is 100% OK and nobody should pressure you into it, ever.
But try to understand that in the vast majority human relationships, hugs and the like are considered normal, healthy behavior. They are not considered a "creepy attack from a creepy creep". I'm not talking about random strangers copping a feel here. I'm talking about close friends and family.
Human touch is very, very important. Read up on Harry Harlow's monkey experiments.
I'm fairly convinced the lack of touch and general warmth in our culture is one reason we all hate and mistrust each other. I realize causes and symptoms get blurry in this arena (correlation vs causation and all of that) but it's fairly obvious people aren't giving or getting enough love and affection in their lives. There's so much hostility, repression, and isolating going on.
