Just a point about this discussion point - just because a situation is worse elsewhere doesn't make it acceptable in tech.

I agree that sometimes it goes a little overboard. But there are also genuine moments when sexist bullshit should be called out for what it is. I don't know anything about the "gallery" tweet, but you need to consider a wide contextual impact of things you say and do, especially when it comes to minority groups. Having a gallery of people involved in the conference is fine, but why bring attractiveness into it? Why not just say "interesting" or "talented" instead? It strikes me as just being a bit thoughtless of the promoters, really.
