We have tens of thousands of highly specialised jobs in our modern societies. Maybe men perform better at some, women at others, and gender makes no difference in still others? If you reject even this question as offensive, how would you know if it's true? It's like dismissing people saying the earth is round as being sacrilegious. If you don't even entertain the question, how would you know whether the earth is flat or round? (I'm not talking about whether he should expressed this opinion at the office or outside, and whether Google should've fired him, but about political correctness in US society. Which seems out of control to me as an Indian.)
