> we’re talking specifically about behaviors done intentionally whose purpose is to signal membership into specific tribes.

Sure, but how do you know what tribes a person identifies with, if multiple groups use the same signals? How do you know an american flag means a proud racist or a proud immigrant (remember citizenship ceremonies are often huge accomplishments that immigrants deeply cherish). How do you know certain clothing styles mean somebody is a proud gang member or just a regular person who's a proud fan of hip hop culture? That's the point of my criticism. I personally am all for taking caution based on prejudice. I'm against people who are only okay with it if it's prejudice against people they dislike, but raise a fuss if people have prejudice against people they like.
