You don't view it as an exclusion of anyone but as inclusion of a minority. Here I disagree, and I do so based on YCombinator previous statements.
"the go-to place where women can speak honestly with each other, deliberately away from the male gender".
If you think a person saying that statement is all about inclusion and not exclusion, I suggest a test. Use such statements about people around you and see how they react. If you are married, tell your partner that you want to go to a party with friends, deliberately away from that person. If they react happily and thank you for being inclusive with your friends then its clearly shown that this is all about being inclusive.
