Except this thread has nothing to do with having or not having an alignment, and everything to do with expressly encouraging other players to judge the actions of other people's characters as Good or Evil in an open forum for all of their roleplay, not just extremes people like to use to justify 'real' alignment.
Yes, we can appeal to people's visceral emotion talking bout murdering little old ladies, but that ignores the 'evils' some people see in things like drinking, diet, sexuality, language, lifestyle, or, say, being judgmental of other people's behavior when it's none of their business.
