You can't beat the drum about social issues and culture.
You can beat the drum about something people don't know, a food drive, a political issue, etc but it makes no sense to keep whingin about something that people already know and have made up their minds about.
Sure they do. Last century it was okay to oppress women and blacks (and even keep the latter as slaves). Times, and people, can change radically.
That said, aside from mentioning the word "penis" in a frankly stupid song, I fail to see how this is sexist. The term is going to lose all meaning if it keeps getting bandied about by such minutiae like this and the beer thing at the California convention.
