Why do some Americans "feel ashamed" for being American even when it's not their fault?

For Context: I'm Chinese American, and I do not feel "ashamed" for my heritage, neither do I feel "ashamed" for being a US Citizen.

The CCP is not my fault. I do not feel any shame of saying I'm from China.

Similarly, the trump admin is not my fault, I voted Harris. I do not feel any shame for being American.
