Hashem Yishmor from what, exactly? I think this conversation is better served on a Cosmetics Blog perhaps, but are you objecting to the DISCUSSION or to the wearing of nail polish by frum females?
If to the discussion itself, I agree this is not the place for talking about various nail polish colors.
But if you object to women beautifying their hands by wearing polish, that is a whole different type of hashkafic discussion, and I am pretty certain women applied all sorts of reddish cosmetic to their hands throughout the ages (i.e., henna). So what is it that you find disconcerting, the discussion on this specific forum, or the fact of the existence of nail polish altogether, in the frum world?
