The two men "were ostracized, belittled and punished for their heterodox political views, and for the added sin of their birth circumstances of being Caucasians and/or males", Harmeet K. Dhillon from the Dhillon Law Group, the lead attorney for the plaintiffs, said in the lawsuit.
But while he wanted more diversity of viewpoints, he wasn't so kind to diversity when it came to gender.
Google spokesman Ty Sheppard previously told CNNMoney that the company has strong policies against workplace retaliation, harassment and discrimination.
The exhibits in Damore's suit include several emails sent to him by other Google employees. The memo said that "genetic differences" may explain "why we don't see equal representation of women in tech and leadership". It circulated widely inside the company and became public over the first weekend in August, causing a furor that amplified the pressure on Google executives to take a more definitive stand. "Google has engaged in some shocking activities in my opinion".
Some legal experts have said Damore faces an uphill battle suing Google.
It accuses the company of failing to protect employees with conservative views, including supporting US President Donald Trump. At least one USA congressman and numerous commentators, some representing the far right, have blasted the company's decision, accusing it of suppressing free speech.
The lawsuit was filed in Santa Clara County Superior Court and comes five months after Google fired Damore for writing a 10-page memo entitled, "Google's Ideological Echo Chamber". Damore, who also filed a complaint with the National Labor Relations Board, appeared to embrace his rising political visibility, posing in a t-shirt with the word "Goolag" written in a multi-colored style that mimicked Google's familiar logo. They claim they were discriminated against because they are both male and Caucasian, and Google's practices favor women and minorities. Google has denied the allegations, arguing that it doesn't have a gender gap in pay.
The lawsuit also accused Google of maintaining a secret blacklist of conservative media personalities who are not allowed inside the company's offices.
White male conservatives have it out for Google.
