Two things:
This is a private business and regardless of the dickishness of the policy, they should have the right to select members as they see fit.
Secondly, can we stop with the "Everyone is beautiful" bullshit? First off, it's not true. More importantly, it's offensive and misogynistic to assume that everyone has to be beautiful or that somehow a woman's highest function is attractiveness. The correct response that doesn't make you look like a dick is "some people are ugly but that's okay because they have a worth outside of their ability to bring about erections." Saying "Deep down, all women are beautiful" is like saying "Deep down, all black people are good at basketball."
