A. I'm not talking about gender-exclusive conferences, nor was the person I responded to (as far as I can tell), nor have I ever heard of such a thing.

B. If you think my English is so poor that I'm unable to properly express myself, then maybe you shouldn't pretend to know what I'm thinking. You only have access to a few of my words, and you've already (actually, literally) indicated that you don't understand them.

So don't be an ass. And maybe take a step back and look at how your behavior supports your broader point.
