I'd like to propose that in addition to disallowing bad words like ****, **** and ****, that we disallow hurting others' feelings. If we're going to have a sanitary community, then there's no reason to stop at four letter words (or longer words like *****). We ought to go the next step and stop nasty talk that hurts people's feelings. After all, people come here to talk bikes... not get their feelings hurt!
