Even though it was the smoking debate that kicked it all off big time, it had been smouldering for some time. It is a matter of lifestyle differences. I also think it is cultural. The couple mostly involved, along with their friend, live in a world (lets be honest, a part of London) where difference is threatening and where the traditional white, working class world (where men dominate, women make the tea and ethnic monorities know their place) is the only world they can relate to. I had had several clashes with lemoneye over the years and the first time it happened he was very nasty indeed because I took exception to what I considered to be a racist remark.
