Birmingham's county is not an independent state from Manchester.
Yes because those are cities. Not states. So you're purposely making a bad comparison.
Scotland and England are partially independent countries, so would be the far more appropriate comparison to different US states. And is why i mentioned them as such in my previous comment.
but we are a federation of countries
No, you are a federation of STATES hence the 'S' in USA, with a couple of exception your states weren't their own countries. Unlike say the UK where Scotland England and Wales have been their own individual countries before unification for longer than there have been white people in the Americas. And now still have their own governments, laws and culture and as such are as or more individual than US states. And it's the same with German states as well and most of my other examples too.
And we are special and different at good, bad, and evil things.
I wish you'd said this at the start so I wouldn't have wasted my time replying to someone that unironically believes in American exceptionalism.
But when outsiders do it based off ignorance, complete ignorance
It's not complete ignorance. I have much better grasp of American internal politics than you do of any other country.
I really wish we left people like you behind on reddit.
