Urgh, I hate the organising assumption too. And if you refuse or make a point that it's never men doing it, then you're a trouble-maker, or horror of horrors, Not A Team Player. Does not apply to men who refuse to organise stuff, of course, if they were even asked so as to be put in a position to have to refuse at all.
On a brighter note, I was listening to some podcasts over the weekend and I've been catching up on the In Our Time history series, which I can unreservedly recommend if you haven't come across it before. It's a sort of panel discussion on chosen topics, chaired by Melvyn Bragg. What I've found particularly enjoyable is the amount of predominantly or wholly female panels, and it struck me how unusual that is for a start, when a lot of panel shows or shows that need to wheel out experts so often seem to be male dominated. More than that, MB actually listens when women talk, he doesn't talk over or interrupt or cut them off or assume he knows more than them. He seems genuinely interested in listening to and learning from women. Of course, he's a very skilled and experienced broadcaster, and this shows whoever he's talking to, but he just struck me as being unusually good at interviewing women. I don't know much about him as person, so please forgive me if he's known to be a raging MCP in his private life 
The contrast was clear when I listened next to the News Quiz which, much as I like it, was, as usual, replete with men talking over women, point-scoring and nicking their jokes.
