@Procrustes,
The thing is, some people have manners , others don't! Then you have people like hawkeye, BillRM and a few others, who are sick and perverted, don't waste your breath on them, it's fruitless.
Everyone has bad days and reacts to certain topics differently. One day you shrug it off, the next you argue and want to see blood.
A2k can be a mine field and it can be quite pleasant, depending how you
maneuver yourself around.
