If that is why Mr. Damore thinks he's being lambasted, he really doesn't get it.
Of course they are not lambasting him in those words (that would be charitable). They are saying ridiculous nonsense like "Google employee claims women are inferior than men" or "Google employee claims women are not suited to be software engineers".
Things he wraps around in cozy wording, but essentially suggests to be true. If not, what's the point of him complaining about outreach efforts? It's not like right now we are in a scenario where, say, 45% of the engineering workforce at Google is female, and Google is trying to force a 50/50 split. It's not even close. Right now the number is 20%, are you telling me it's settled science that should be the ratio? Because if you have hard numbers proving that's the case, then by all means, Google is wasting money in outreach efforts. You should tell them right now.
As much as I disagree with his viewpoint I seriously doubt this would have been terribly big deal if he had approached the issue with more tact, at minimum.
Or is it because he is able to make a cogent argument against blind dogma and fanatical ideology?
The basis of his argument is that, with regards to hiring processes, we should treat people as individuals rather than just another member of a group. Furthermore he squarely targets neo-Marxist social constructivist ideology that divides society into oppressors and oppressed, claiming it is a flawed methodology to base your company's business on.
His worldview is fundamentally different from that of his opponents, and he makes no bones about it.
I don't think he thinks that. At least not if we are to believe the memo.
However I do think many of the responses took offence with the idea of biological differences between men and women. And maybe rightly so, since some of them referred to seemingly good research showing that he at least overstated his claims.
What many of the responders don't seem to get, is that a good reply shouldn't dependent on whether differences exist or not. Instead it should tackle the question of how we treat different people equally. When should we try and level the playing field, and when should we accept that gender gaps (and other kinds of gaps) appear?
