This is what I saw growing up in rural Ohio. Many HS classmates moved out of state and others moved into the major urban centers of Ohio.
A thing I like to say is that I am proud that I am from Ohio, but I'm also happy I'm not there now.
I’m from Florida but it’s not something I’m proud or not proud of. I’m proud of my kids. I’m proud of my work. I’m proud of my multi decade relationship with my wife. Those are things to be proud of.
When a class I belong to does something great, I feel I can only be proud to be a member of that class to the extent that I contributed to the great thing and that we worked together to achieve something greater than ourselves. Even then I’m proud that “we did that thing” not that “I’m a member of that group.”
Just a thought. I know many people are proud of where they are from but it’s irrational to me.
