>I check the social media profiles of their prominent engineers and search with keywords like "feminism", "women" and "she". See how they talk about women in the field, whether they follow women on Twitter, whether they posted angry anti-Hillary memes.

By diversity you (and many others) actually mean "people who are followers of/subservient to my ideology and preferably in a different shade than male and pale". The world is not a university campus where you can be sheltered from conflicting opinions. There are all kinds of humans out there who are good and decent, and some of them don't even tweet about feminism, believe it or not. Your zealous reluctance to work with someone because they posted the wrong memes in their spare time is incredibly infantile and unprofessional. You're not against "mono-culture" (you're even actively looking to stay within your bubble), you're against mono-cultures that aren't yours. At least be honest enough to admit that rather than operate under this false pretence of being virtuous.

>if my boss is going to be a white dude, he had better have publicly condemned sexism in a way that feels constructive and genuine to me.

If my boss is going to be a black woman, she had better publicly condemned theft in a way that feels constructive and genuine to me.

This thread is straight out of a dystopian novel, where "white dude" is said in disgust and the wellness of a place is judged by how few straight white males are there. I hope the irony is not lost on you and the other champions of anti-isms in this thread.
