ELI5: why is it considered disrespectful to wear a hat during the national anthem in America?
gpt
Fundamentally goes back to Christianity as practiced years ago.

When praying or prophesying, men were to have their heads uncovered.  Women were to have their heads covered in the same circumstances.

Thus, the removing of hats when someone died in westerns, etc - you were praying, and thus removed your headgear.  Likewise, the hats you see in depictions of African-American women (most famously) in church - same basic thing.

So, by extension, removing your hat became a sign of respect for men.  Hasn't translated into secular terms quite the same for women for whatever reason.
