Ok, let's say you're somewhere and some guy grabs your mother's, sister's, or daughter's ass?
Or, he goes for all three. You're just doing to stand there and not demand an apology? Just pretend it didn't happen? I'm sure they'll love it and decide you did the right thing
Don't accept second class treatment. Be confident, be a Man.
I didn't ask you for a speech on confidence, I asked you what your next move would be if he didn't apologize as you demanded? I take it from your response you would hit him. See, I don't think your demand of an apology is going to do anything except force a physical confrontation, unless as I said he is clearly smaller than you. I might also point out that this thread started with a guy making a remark about your girl's boobs, and now your bringing up somebody grabbing your daughter's ass? Whole different case there.
This actually happened to me when I was about 27. I took a date to a party, she was an HB9, and some drunk dude there started getting a little handsy with her, and she was protesting. I didn't hit him, but I took him down to the ground, put a hold on him, and made him assure me he would act appropriately before I let him up. You might have been proud of me, but I felt like an @ss, and I don't think it won me any points with the girl either. I think she thought it was brutish and disgusting. Back then I was quicker to violence, now that I'm older I probably would avoid it. Maybe step between them and say "whoa, hands off the merchandise" or something like that.
I keep thinking what if it's a guy like my buddy who is huge and ripped? Because that sounds like JUST the sort of thing he would do when he drinks. The thought of me attacking him seems laughable because there's little doubt he would crush me, it would be like me jumping Ray Lewis. I guess I could start chopping at the ankles and work my way up. Getting your @ss beat doesn't seem like it's going to prove to your girl that you're alpha.
But I agree you can't just let some guy maul your girlfriend. As Kenny Rodgers said "sometimes you have to fight when you're a man". The problem I have with your "demand an apology" approach is it almost ensures a fight. I would be most concerned about legal actions against me (as opposed to getting beat up) if I were to actually initiate the physical contact. It doesn't seem like a good idea.
