I think the organizer should have been upfront with you about what he/she wanted you to talk on. That said, I don't think it was an offensive request. The organizer wasn't being presumptuous that you would be interested in speaking on this topic just because you're female -- he/she was merely asking you... As a woman in tech, I get how it's these little things compounded over time that get annoying, but this ask on its own is not unreasonable is it? You can always just say no (as you did). :)

I think it was more disappointment at not being asked to speak about what she wanted to speak about.

Yeah, I wasn't offended. I was disappointed.
