You're being purposefully obtuse and dim, but I'll respond once more incase you are actually trying to understand the world around you instead of ragebait.

We have "heroes" we celebrate, mythicize, and owe the US's history to which I would qualify as American. We're not talking about "blaming the US for government sanctioned activities", we're talking about what the fuckin comic is talking about which is the history of American heroes. So no, youre not even commenting on the correct concept.

This is completely ignoring the fact that "American" is a bit of a erasure of the reality that Native Americans were American, Canadians and Mexicans live on North America. There's a whole other fuckin continent called America whose residents should be considered American... But that's a bit pedantic even if there's some meaningful lessons there I'll drop that topic to focus on what's actually more telling.

We have a holiday for Christopher Columbus. I grew up learning about him for multiple years of my history education as the person who discovered America, viewed in a positive light despite what he did. Benjamin Franklin, one of the beloved heroic founders, was born in like 1706 putting a ton of his actions and horrific behaviors prior to the founding the USA. There are several characters like Pocahontas and Captain John Smith that we again point to and learn about as heroes in the American Mythos. Idk if I'd consider them citizens of the USA but I would definitely consider them Americans. Like first of all is 320 years (BF's birthday to today) so off from 400 that you'd make a comment? Is drawing a line at what Christopher Columbus did as not American really so important to you, given we have events like the Trail of Tears taught in every classroom in the US. It's all an extension of the same evils you're erasing accountability for over less than 100 years? Like it's just weird man. Big touch grass energy. Is it cause your identity is tied to Americans doing no wrong? Or are you just bored today? Like I'm genuinely curious, I'm not exactly interested in being your therapist, but like wtf is this worth to you?
