No, you did not. You proposed no solution to entrenched and systemic racism.
Then you're wrong, and thus this demonstrates the fundamental flaw with your approach to this topic: it prevents you from seeing, understanding and accepting reality.
This addresses nothing, it just sweeps the issue under the carpet and pretends it is an issue of "individuls getting better".
It is not an individual choice that results in the disproportionately negative effects of poverty, policing, healthcare, welfare and representation falling most heavily on minority racial and social groups. It is direct result of historical and systemic racism.
Your attitude doesn't address this problem, it just ignores it to make yourself feel superior. But these problems are real, and they negatively impact the lives of many people. If you think it is unfair that a person should be, on average, poorer, more likely to be stopped by police, more likely to be found guilty of a crime, more likely to be shot by police, more likely to serve a longer prison sentence, less likely to get work, less likely to be able to obtain positions of power and more likely to die of preventable diseases - all just because of the colour of their skin - then you have to address that problem and admit that maybe you aren't all that superior.
But you'd rather just pretend thay all of that is just up to "individuals", which ultimately just means that you think minorities bring it on themselves, and you don't have to do or think anything about it. You'd rather generations more people felt the injustice of the lingering effects of historical racism than admit that there is a power imbalance that we ca actually, actively do something about.
You are a perfect example of why your ideology is wrong.
