@engineer,
Thank you engineer, for a well reasoned post.
1. First of all, I am not in lockstep agreement with this guy's point of view (although I will go as far to say that some of his arguments have more merit than people are willing to admit). My main argument is that he should not have been fired, and that the fervent attempts being made by the left to stifle any discussion on these issues are counter-productive.
2. Are you arguing that they should be locked out of employment? I strongly disagree with you if you are going to tell people with the wrong opinions that they can never be engineers. I think we agree that the number of people with ideas that are considered "offensive" is pretty high.
If you are arguing that they can be engineers, but that they have to stifle their opinions on the job... is this better for the a work environment, or worse? I think I prefer to work in an environment where people can speak their mind and work out differences of opinion.
3. You might want to think twice before you state what "any woman" would do. I would feel uncomfortable stating what a "woman in her right mind" might or might not think (and people here say I am a misogynist). The liberal ideological echo chamber has always had trouble explaining why there are so many women who choose to be conservatives.
You are taking your argument too far when you say "There is no way, ever, that individuals will feel that way". This is demonstrably wrong; female engineers have gone on record to say otherwise (including one on NPR yesterday morning).
4. I accept that many women will feel uncomfortable by this rhetoric. And, I accept that this is a weakness in my argument. However, I feel that the cost of enforcing an ideological viewpoint by an employer is too high.
5. I think you are overstating the position that this man took in his essay. Yes, he said that women "on average" are less suited for engineering.
6. I think that arguments which conflate race and gender are completely bogus. Race and Gender are very different. In the realm of science there is respectable research from mainstream scientific organizations on the role of gender in cognitive processes. This is considered a legitimate field of study by the scientific community.
In the realm of history there absolutely no comparison to what African-Americans and Native Americans endured to what White women endured. Race has always been the primary factor in the US.
