The truth is that if you are on the "left" your blind to what many are thinking. In person I will never tell you the bias or problems I see. I've learned doing so would make it nearly impossible to work with you.
Not saying you are "wrong" but the problem I an many like me face is that the softpower pressure to conform to left ideals mean I never do or say anything because I assume everyone around me would push back or push me out.
It's partly paranoia but it's also part of a factual experience I've had in highly liberal environments. They don't want to hear it and if they do you are damaged. Very different from the people we all know who are expounding and preaching liberal ideals in ever conversation they have.
