UNITED NEWS INTERNATIONAL (UNI) — A former Google employee fired over a memo criticizing the company’s diversity policies has filed a lawsuit against the tech giant.

James Damore’s class action suit, which has been joined by another ex-employee, alleges Google discriminated against conservatives, white people and men.

Damore happens to be all three.

His lawyer, Harmeet Dhillon, said Jan. 8 this lawsuit is about changing attitudes in silicon valley. Dhillon said, “Now the only acceptable form of discrimination, where everything else is eliminated, is it’s ok to disparage, smear, belittle, bully, discriminate conservatives and white men. That’s not acceptable.”

Damore’s controversial memo included claims that biological differences factor into the shortage of women in tech and leadership positions.

At the time, CEO Sundar Pichai said portions of it advanced “harmful gender stereotypes.”

In response to the lawsuit, a Google spokesperson said only that the company looks forward to defending against it in court.
