I think what this Advice memo is about isn't the idea itself, but how he poorly he handled the idea. The disruptive way he handled the idea is not protected from being fired in an at-will employment company. Google even worded that in the termination:

>Your post advanced and relied on offensive gender stereotypes to suggest that women cannot be successful in the same kinds of jobs at Google as men. I want to make clear that our decision is based solely on the part of your post that generalizes and advances stereotypes about women versus men. It is not based in any way on the portions of your post that discuss Google's programs or trainings, or how Google can improve its inclusion of differing political views. Those are important points. I also want to be clear that this is not about you expressing yourself on political issues or having political views that are different than others at the company. Having a different political view is absolutely fine. Advancing gender stereotypes is not.
