Normal human behavior.
Well then I guess I and other people who think it's stupid to be proud of skin color or what sex organs you were born with aren't "normal"
Correct.
It is normal and healthy to be proud of all kinds of things you have not control over. TO be proud of your nation, or your city, or your school, or your parents.
It is not normal and sick to NOT have such feelings, or worse to consider such feelings to be wrong.
No it's not.
Why be proud that you have blue eyes unless it's because you think you're better than people with brown eyes?
And you do realize that the fact that you were born on this particular patch of dirt doesn't make you any different from any other person born on a different patch of dirt?
It is not about the dirt. It is about the people who are part of your group. It is normal and healthy to be proud of the group you are a member of.
It is part of the social dynamics of a healthy group, that allows it to work together, for the good of it's members.
so what is the difference between your comment and playing identity politics?
A fair question.
1. THe most obvious is that the above description is does not restrict the group in question to an particular identity, and can easily be expanded to include others, indeed, bringing very different groups together.
The "piece of dirt" idea that Bluesman attacked for example, often manifests as "nationalism" which is about getting the various groups in a nation to unify to work together towards common interests and goals.
