Let me present a moderate disagreement. I dislike events like this because it can't be made universal. Let say we had a common rule that said: any industry has this bad gender segregation should have exclusive events for the minority gender. Given a 80/20 ratio, this would result in around 30% of all industries which employs about 40% of all people in my nation. A significant amount of events would turn either exclusive male or female, with the majority being exclusive male, and I personally doubt it would have a positive outcome on society. I am open to be convinced otherwise.
