You can’t enforce behavior in traffic, but you can enforce it in your living room. If you are hosting a blog then what’s wrong with demanding that people follow a set of guidelines. Somebody can swear at you from the window of their mini-van but if they curse you out in your kitchen you can always ask them to leave.

I miss the point of the analogy of the old woman at church…is it that people who don’t attend Mass EVERY week are rude? ;)
