When you say “pride in hypotetycal tribal bands that may have never existed” what do you mean? You don’t believe that human beings evolved in tribes or don’t believe the members of these tribes felt a sense of common well-being that we call “pride” which have helped our evolution?
You’re comparing two things:
Actually observed collective pride in nations
Pride in hypothetical tribal bands that may have never existed
And saying the first is “silly” but the second is what we’re built for.
Understanding collective pride in its actual form is less silly than pushing into some dreamed-of past.
