The dude has some serious misconceptions about the world and people, but I think his heart is in the right place. He's working from some bad assumptions and has come to bad conclusions as a result. It's classic Garbage-In-Garbage-Out.
I'd really like to see the Goog take this as an opportunity to really reach out to this guy (and hopefully all the other software bros who give enough of a fuck to pay attention) and help him understand better. If they can get through to him, they will have a very persuasive proponent of reform on their hands.
Also, treating this guy with respect and not firing him outright will demonstrate that open conversation about important issues is allowed at Google.
And, in case it sounds like I agree with Mr. Bro Grammer, "wimmins is soo emotional", I think the gentleman needs a solid walloping with a clue-stick.
