No, I believe the author did that when he said that diversity programs alienate non-progressives.

You at least agree that there are different types of diversity programs. (From his claims) Google's approach to diversity are hamfisted and end up achieving a level of diversity that looks good on internal reports but ends up alienating people because it's more important what you are than who you are.

If a non-progressive is alienated by a diversity program, are they not a racist or sexist?

Not all diversity program are created equal, heh.

Diversity through quotas or hiring preferences to X, Y, Z classes of people are bound to make people angry.

Diversity though increased access to education, recruitment efforts, and accommodation of different strengths and weaknesses, personalities, work styles, management styles, etc. would make people much happier.

We have a mandated bible study program covering the ten commandments.

Oh that alienates you? So you want to murder people and steal stuff? We are going to fire/blacklist you now as a thief.

No. Maybe we just believe in equality for all regardless of race or sex. If a cool course opens but only for women, or people of color, of course that makes us feel alienated.
