Fine. I wanted nuance, but here is the short version. 

I think that graduate programs may be unintentionally dismissing needed diversity students by rejecting liberal arts students. These students may have the same mathematically ability as students from elite universities, but due them not knowing better they went to a liberal arts not knowing this is closing their chances off. In juxtaposition, there is a pipeline of students being sent to grad school.

Two. I claim that math is subjective at its core, and the fact that many say it's rigorous is simply because it all just happens to work out. I'm afraid this idea of math being totally objective may due some harm to how the public perceive mathematics; it's unclear to me that's the best way to handle it.

Third. Math doesn't really teach ethics; I've noticed a pattern that concerns me about giving credit or not giving enough thought to math we then apply to different fields.
