I have seen this before especially in immigrant communities to the US. It has baffled me. Has there been any introspection as to why natural born people are not as blindly patriotic to their country? My theory is that they understand that a country like the US only earned all of its amazing rights and freedom due to generations of people pushing against the status quo and that invokes the same non-pride as people are feeling today. Immigrants have not gone through the same upbringing as natural born citizens. As a result, they have a more rosy view of reality. It takes some group of people not to accept what is reality today to forge a better future. For example: BLM is heavily villainized by some groups in the US. Time will tell what the long term consequences of BLM will be(if any). But maybe we will look back decades from now when there is a turning point in the country and there ends up being equal justice and treatment for Black and Brown communities and maybe we will remember BLM as a contributor of change(but not the anti-US sentiment that went along with it).
