There is no connection whatsoever between diversity and building product. Note: you haven't tried to explain your claim there is, just implied it's obvious, probably because you can't. I've seen people try to honestly intellectually defend a connection between employee diversity and product design before, and it's always a joke. You get anecdotes about face recognition not working on black people (reality: the software in question just had trouble with low contrast images and also struggled with white people's faces). And that's about it. I can't recall ever seeing someone actually argue that more women == better product because, well, that's a pretty sexist thing to believe isn't it? It implies men have no empathy, or that there's a universe of product requirements women will only tell to other women, etc.
If discrimination is happening against an individual and you work with the management chain to resolve it, that's not a political act, because you aren't attempting to radically remake the entire organisation for everyone (politics), but only address the specific problem that was actually observed.
