I'm among the older ones here, and I have no problem whatsoever shaking hands (unless, of course, the person's hands are real sweaty----UGH----but you can't wipe them on your jeans, or anything, that's socially unacceptable, but it gives me the willies). I guess because I was taught as a kid that it "shows good character" (I'm a girl, so I wasn't told it would show I'm a good man). I also get a feeling of disgust, really, when someone has a limp handshake----INSTANTLY I have judged them as a weak person-----ESPECIALLY if it's a woman, I wanna smack her (not literally, of course). I have TRIED to re-think that philosophy, however, and just say "they haven't been taught differently, that's all." I haven't been successful, so far, though----like I said ESPECIALLY if it's a woman, I automatically think "Grow a backbone, will ya, already!"
As for the hugging thing: I think there was confusion because the OP seemed to defeat his own argument by giving examples of when men DO have physical contact other than a handshake-----but, there was a point made regarding "friends and family" vs. strangers. I don't know if that was made clear, as almost every proceeding post gave examples of family and friends, hugging. I, TOO, have seen lots of men hugging----but, they all knew each other / were related. I don't think I've ever seen strangers hug each other----unless, maybe, it's some group therapy, maybe, or something like that?
