To change what it implies, to change what it’s associated with, to change what it symbolizes.

The phenomena I describe is much broader than the US and the current time period. It has existed across time and cultures, implying that there are broader factors at play than the opinions and behaviors of contemporary US culture. Flag waving nationalism is damn near universal. Americans only differ by how universally people feel the need to wave the flag.

My greater point is that you can't change what the flag symbolizes by having different opinions and flying the flag. Symbols are just that: symbols. To change what the flag means you must either change what the US does or change the flag. Embracing national symbols only emboldens nationalism if your nation isn't diametrically opposed to nationalism.

“That’s ours, we own it and it represents our values. See it flying everywhere? That’s because we own this nation, we’re the one’s in charge here, not you”

This is quite literally true and always has been. You don't see flags representing the Lakota or Seneca nations anywhere, and the 13 stripes are a direct hat nod to the European colonization wiped them out. The state will not stop systematically repressing indigenous, black, or other marginalized peoples if progressives suddenly start identifying with the flag. It will just make progressives look supporters or useful idiots to that state oppression.

Why would I want to prevent right-wingers from taking sole ownership of something intended to represent a state with long history of right-wing violence, slavery, and military interventionism? They can have it. It's as perfect of a symbol for right-wingers as any other. Should we fly the swastika to reclaim it too?
