So... you don't have anything actually to suggest? I'm having a hard time figuring out how what I know of PUA could be applied to getting women to come to meetups. From what I've seen, it's pretty specialized to getting women to sleep with you.

Maybe you should start by trying to figure out actual helpful suggestions, and then we can worry about whether people will be offended by them.

(BTW: my older brother is depressed by his lack of success with women. I'd like to point him toward some helpful seduction resources but 1) I don't know how to do this without embarrassing him because, you know, it's dating advice from his younger sister and 2) I know a significant subset of that stuff is really kind of misogynist and nasty, and I'd rather not support that. Anyone have any brilliant ideas?)
