What of Google managers quoted in media vehemently saying they wouldn't hire people harboring certain political positions? Why is it that so many of my acquaintances who work at Google pig-piled James Damore over his professional competence, despite none of them being in a position to have any idea about that? All of this smacks of a degree of ideological groupthink I would label as "virulent."
What you are saying would still fit if the overwhelming majority of Google had a large political skew and subscribed to a particular ideological groupthink. The majority would feel that, "people share their views openly, a wide range of opinions are respectfully shared, most people have the right to get into and stay out of political discussions," since conversations about things everyone agrees with can only go so far without an "enemy" who disagrees. A minority in that situation would still feel oppressed. It's how well minorities are treated which is the true indication of how open and benevolent an organization is.
