There are various manifestations of these atrocious manners, but they seem (to me, at least) to boil down to an inability, on the part of certain men, to take ‘no’ for an answer. I think this is tied to participation in various ‘geek’ subcultures (both on-line and off-line, so while it may be convenient to blame the internet, blaming the internet is unfair). Participation in these varied subcultures is seen to give people something of a pass for rudeness. The justification proffered is that participation in the subculture resulted in bullying when the man in question was young, conferring victim status on him as an adult. And, as I’ve pointed out elsewhere on this blog, wrapping oneself in victimhood is often a way to avoid having to take personal responsibility–for anything.
