Couple-o-thoughts..........
Good on you for apologising. If you felt it was warranted, I respect that.
On the bit about people getting upset - Well yeah that happens.
Not everyone is going to agree with everyone else all the time.
Hell, if they did we would never learn.
I disagree with people quite often, but I also respect their opinion even if I think they are clearly wrong. I have been wrong many times before and will no doubt happen many more, so I want to be given the same respect for my beliefs.
On the whole Nipple front - Well I think you're on the wrong forum for that kinda talk..........

Go on, keep living and having fun............
Cheers and beers
Brian
