> I’m absolutely convinced that not all people can learn algebra or calculus. To me it is obvious this is so since the mentally disabled can’t.
Not all people can read, it's obvious since the mentally disabled can't. Yet with proper education, all non-disabled people can be taught reading.
But that doesn't mean everyone can read, if you're illiterate by your 20s, you're gonna have a hard time catching up. Same for mathematics: most people reaching even high school are too mathematically illiterate to catch up[1]. Is genetics a factor: definitely, but it's among many others.
The reason why it's a partisan issue is the following: if I say genetics is a decisive factor, then I can say «it's natural, there's nothing we can do so we don't need to spend all that government money trying to help those people». The left-sided point of view goes as «There's nothing we can do about genetics, but we can change everything else. Then we need to find what are all the other factors, because those are the actionable ones». The conservative focus on genetics is mainly a justification for doing nothing.
> There’s a level of “intelligence” that’s necessary to learn a given topic. Not everyone can learn all topics.
“intelligence” is conveniently pretty ill-defined, but I don't think I'm more intelligent than my doctor friends, yet they struggled a lot to grasp even the most basic concepts of algebra when I tried to help them during our studies. “Not everyone can learn all topic” but I have yet to find evidences that your ability to learn a random topic you're not interested into is correlated with the common acceptance of the word “intelligence”.
[1]: that doesn't mean it's impossible, just likely well beyond the amount of effort they can (or want to) afford.
