I must say I do sometimes read MN and conjour up a mental image of one or two posters being in their late 40's, living in their Parent's basement. Obese and floral dress wearing, surrounded by empty take-away cartons and Diet Coke bottles...thick yellowing toenails and legs that haven't seen a razor since that one day they lost their internet connection and had to venture to the Chemist for a bottle of Kalms.
These are the people who trawl internet sites daily...reading every thread and actively looking for something to be mortally offended by.
It's usually quite obvious when something is posted to cause offence but some people really would find offence in an empty room with no windows.
