"The [James Damore] lawsuit claims that numerous Google managers maintained 'blacklists' of conservative employees with whom they refused to work..."

"... that Google has a list of conservatives who are banned from visiting the campus; and that Google’s firings of Damore and the other named plaintiff, David Gudeman, were discriminatory... The company’s workforce, like much of the rest of the tech industry, is overwhelmingly white, Asian, and male.... But the Damore lawsuit purports to expose a cultural bias toward promoting diversity and 'social justice' that, the suit claims, has created a 'protected, distorted bubble of groupthink.'... Internal posts discussing the debate around diversity at Google, such as a meme of a penguin with the text 'If you want to increase diversity at Google fire all the bigoted white men,' are filed as an appendix to the lawsuit under the heading 'Anti-Caucasian postings.'..."
