1. I thought gender-based discrimination was illegal. How is Leap not illegal?
2. One of the main objections of "gentleman's clubs" was that their (male) members had access to important networking contacts, putting women in unequal foot in an unfair way when it came to businesses. Wouldn't Leap be unfair in the same way?
I think you could argue that Leap is somewhat similar to that. It's a support network for a group of people who face a particular challenge and need a safe place to talk.
