actually if you think about it, women would actually have a leg up when it comes to getting funding etc. Since there are so few of them, they have a much higher chance of actually getting to talk about their idea in front of VCs who want to see what they have to offer.
Presentations are a cost. If they won't lead to funding, they give information to the VCs, they waste your time, and they get your hopes up and then slowly disappoint you.
If being a curiosity gives a negative first impression, this likely outweighs any additional time to speak.
