I don't know which part you don't believe but it seems you are mixing two points together. The first point is that math has reached a point where it is too complex for us to understand so we have started using our imagination to pretend that whatever bullshit a mathematician can come up with is real and valuable. This is a point which you have just proven with this: "Because it isn't even limited by reality." We literally agree that math has left reality behind. Some people want to go off into this world of imaginary, unhinged from reality, math and construct some theory (like string theory) and then claim it is in fact what reality is and everyone who disagrees is the stupid one. Go and do your imaginary math, but don't turn around later and claim it describes reality.

The second point is that all of science is under attack by political and ideological forces, and that is not an opinion. I am not the one who invented the claim that math is a form of white supremacy, that is a claim literally made by mainstream professors, and not challenged by any establishment. It is a fact that wokeness is being pushed everywhere, including math. When there are math questions written with a woke premise like "if the prison population has x amount of black inmates and x amount of white inmates and the general pop has x amount of one and the other by what percentage is the black population over represented" this is reinforcing woke propaganda. This shit is now the norm and if you don't believe that you have once again left reality behind.
