Why is the initial reaction to any type of women's division in pinball:
"They don't need it, there is no advantage that men have over women that warrants a separate division"
That isn't the point and generally speaking is not the intention of any women's division I've ever seen run IMO.
Fact: There is a major imbalance in the pinball community from the perspective of how many women there are in the community compared directly to the number of males.
The idea behind a women's division is not segregation, it is recognition and awareness. It is a way to foster a fledgling group of people in our community and ideally create more interest in the hobby as a result.
The major difference between women and men in pinball isn't skill or ability, it's strictly a numbers game. So how do you increase the numbers? By drawing attention to it. The point of the division would be to say "Hey look at these awesome people, don't you want to be as awesome as they are? Well if you do all you have to do is play!"
When the community gets to a point where the ratio of women to men is more like 60/40 rather than the 90/10 it currently is then I could see the argument that a women's division would no longer be necessary. But until then there is 100% value in running something like this.
