It's not that I understand that some women feel naked without their makeup, it's that I think that they should be pissed that they feel that way, because makeup is bullshit. It's something forced on women for no particular reason except social norms and that men like their chicks painted.
I support feminist crusades against makeup and body hair shaving (or at least equality in body hair shaving.) And I personally think most women look more attractive out of makeup than in it. Zits, uneven skin tone, wrinkles...all are part of what makes a person a person. And I am attracted to human females. So why paint over their humanity?
