In his article “By Firing the Google Memo Author, the Company Confirms His Thesis” David Harsanyi identifies three thought crimes of the modern age:

The problem isn’t diversity; it’s that a senior software engineer admitted, perhaps unwittingly, to pondering three of the most scandalous thought crimes of contemporary American society.

1. The first thought crime is proposing that a meritocracy might be heathier for a company than bean-counting race, ethnicity and sex.

2. The second thought crime is pointing out that ideological diversity matters.

3. The third and most grievous thought crime of all is suggesting that men and women are, in general, physiologically and psychologically different, and thus they tend to excel at different things.

By firing Damore, Google confirms much of what he warns about.
