I think it is an overblown and mostly false stereotype that coders are foul-smelling. I've never actually met a foul-smelling coder. Ill-dressed, yes. But we mostly work in offices with air-conditioning, there isn't much sweating going on. All of my current and former coworkers seemed to wear antiperspirant and deodorant, and so do I.

As for "whack job", this is the kind of language that disparages our industry and unnecessarily lowers our social status. Would a doctor or lawyer take being called a "whack job" by default so lightly?
