I’ve taught mathematics at community colleges for over 20 years and I’m absolutely convinced that not all people can learn algebra or calculus.
It's obviously genetic, says the mathemetician.
I tried once to ask reddit's Anthropologists about what cultural artifacts are affected by genetics e.g. how lactose intolerance can affect a local culture. The question was apparently racist and then taken down.
I once asked an obvious lead in to a racist argument and was called a racist. It must be a conspiracy.

You write web servers that need more boxes and serve less traffic than was standard 10 years ago. Why would anyone listen to you on any topic.
I am convinced that some people can't learn algebra and calculus, just like some people are not able to read visually. However those cases are rare and when we properly have inclusion it doesn't matter.
Totally with you in terms of the school system instilling fear and acting as filter against self motivated people who wouldn't accept sitting in an office for 10 hours on end.
