You should watch Stefan Molymeme's interviews and shows with experts on IQ. And also read The Bell Curve if you haven't yet. It seems to me that the situation is less hopeful in terms of IQ improvement than you suggest. IQ looks to be about 80% genetic, with the remaining 20% basically impossible to account for in terms of environment or culture.
Even if it were only 40% genetic, it still doesn't bode well for IQ improvement. Just because it's not genetic doesn't mean it's not heritable. For example: most people speak the same language as their parents, even though it's not transferred genetically. And once IQ "sets" in a person around age 16-19, it doesn't change. So, low IQ parents will tend to raise low IQ children and so on, even if it's not purely genetic.
You've made several mistakes.
Racism is judging a person based solely on their race. That's not what we're talking about. We're talking about mean differences in scientifically measurable quantities that are proven to differ, on AVERAGE, between populations.
Also, you seem to believe that you can judge an individual based on aggregate data. You can't. You can only judge mass populations based off of statistics. You can only judge an individual based off of conversation or their own actions.
You are the one who brought up "dumb niggers", not any of us talking about measured IQ differences.
Asians test better than whites on visual-spatial but a little lower on verbal abilities. Even on tests designed by east Asians.
Ashkenazi Jews test higher (shockingly higher) on verbal abilities than whites, and only about the same on visual spatial.

I don't have the time to explain why you're wrong here too. I've gotta go, but if you're curious, I recommend reading The Bell Curve (written by two Harvard psychologists, not politicians) and Stefan Molyneaux's expert interviews on IQ.
And before you assume I'm a white supremacist you should know I'm Hispanic, kek.
