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.
So what is the thought process of people feeling shame/guilt?
That only happens in the US because of first past the post system. In European countries new parties with significant vote share are created all the time.
In fact, in my country the opposite of what you say happened. First we had a dictatorship with a single party. Then democracy came and we had a 2 party system. No we have 4 major parties, in addition to some minor ones.
