To your point about being blind to what many around me are thinking- by definition, I wouldn't know if I was, right? So I'm not going to try and argue one way or another about that. I will say, however, that I have worked with many colleagues with whom I disagreed about many different things, some of which fall under the general umbrella of what one might call "identity politics", and as a general rule have been able to have open and civilized conversations with them. One thing I have learned is to not make any assumptions about what somebody does or doesn't think about a given topic, as basically every time I've done that I have been surprised.
