Well, it didn't come out as good as I thought it would - but I hope you enjoy it, or get a laugh out of it.
The skinny: Some bone-head with either a philosophy degree, or some fuzzy-soft science degree wrote an essay about nice guys not "really" being nice.
1. If they are not really nice, then a different adjective should be used to describe them - the fault lies in the person making the claim. It's as jack-assed as saying, "round balls aren't really round", or "green cars aren't really green".
2. The feminist point is - you, as a man, are not allowed to morally judge your own character. It is up to a woman to point out all of your flaws. How dare you not constantly put yourself down - or let others judge you (i.e. put women in a position of moral authority above yourself).
I am sure that other things can be added to this list, but, ultimately, this is one of the ways that feminism is trying to revamp the English language - so that fewer POSITIVE adjectives can be used to describe men and boys.
This has already infected our society - as if you say "nice guy", many women have a negative reaction to it...
Anyhoo - enjoy the old crusty film composed of bits and pieces of vintage public domain footage.
