Now that's clear, it really is a case of personal opinion of what's acceptable or not. I personally think not, you think so. Fair play.
I assume then, if one of your family members, or yourself got drunk at the pub, to be held up against the wall by 3 other men, if they deem it appropriate, they can headbutt you in the face if they think you deserve it?
Don't talk daft, I would never threaten with a knife. You really do say stupid things.
