To answer your question, I didn't actively consider diversity in tech a problem before. So I think you have a point that it's good people have brought it up.
However, that doesn't mean I always agree with the means of social justice. It is possible to fight for a good cause in a bad way.
So there are multiple facets to this issue. I believe in the endgame of social progress while still siding with Dalmore. I think the correct way to refute Dalmores of the world is with research not firings, and people who would have him fired I think are doing the wrong thing, for the right reason.
That said, from what I've heard it sounded like google had a fine program in place. I think we're on the right track at a good pace for women in tech.
I'd like to see people start talking about minorities in investment banking next, because I'm not hearing it.
