IMO this list was started as an inclusive forum for discussion of gender gap among equal participants. Discrimination by gender doesn't make sense to me. My vote goes to common sense rules, election of a male and female moderator, and enforcement of those rules into actual practice (without discrimination by gender). In other words, egalitarianism and sensible moderation.
If people want to run female-only lists or groups, I think that can be useful and good, but should be done separately.
