i know plenty of guys who would like a grant to attend conferences. How is this not sexist?
Assuming you're male, do you feel discriminated because Google wants more women to attend conferences? I don't.
Now if the site would say that men in general shouldn't bother going to tech conferences, and if the majority of society would agree that men shouldn't bother getting into tech at all, then it would be discriminating. We're quite far from that.
And I have only once gone to an expensive conference. I offered to help with organization and running it and therefore got in for free (paid own travel expenses).
