I'm asking why he thinks that different gender ratio would be a big change. Are men and women so different from each other that it would be noticeable? Even if the discussions are strictly about rationalism?

I'm also asking why he thinks change like that wont happen. Are women inherently less rationalistic?

And a question for you: why it is likely that people who want to join have that skewed sex ratio?

(Disclaimer: I'm asking these questions because I'm interested in what people think, and I'm trying to keep them as "unthreatening" as possible. But as they are questions, they always seem somewhat aggressive :P)
