I hate to extrapolate data as an idiotic internetter but being born in the US and being illiterate could also be because
The thing is that so often people who have no clue about things and the real living situations of people do talk down on people who are experts about those questions or affected. Effectively a lot of what you did was muddying the water and thus implicitly justifying that there might be good or acceptable reasons.
You were nationalist and you were racist with that and you were also ignorant of your own history and by being that ignorant you again actively(!) marginalized the BIPoC people in the US, as well as muddied class. In your other answers you were ableist and not kind either. You could’ve been kind, but you weren’t.
Lol damn you don’t have to call me a racist
Well then don’t act like one. Don’t try to defend faults of your country, try to help the people affected by the faults. Listen to affected people and listen to experts. This is a chance to grow for you. You can be kind and you can create a welcoming place for others. To do that you would need some collective work though and maybe read How To Become an Anti-Racist (and you could also watch the liberal lecture series by Robert Reich to get more how red lining works).
Consider posting what you did.
