Your example is of a politician who believed that everyone of a certain genetic disposition was dangerous.
I don't think there was even a subtext to the term superpredator that meant all non-whites were dangerous. It was explicitly used to target a certain type of behavior.
Your anti-mutant politician wanted all mutants incarcerated. A politician against gang violence wants people who engage in gang violence incarcerated.
HRC wasnt a politician when she deemed black youth "super preditors" and the mass incarceration of black youth "super preditors" have not cured gang violence and it never will.
Unfortunately now she comes off as a white politician who regressed into whitesplaining the issues surrounding the black community at her plantation style fundraising dinner filled with predominantly rich white people that felt compelled to hiss and moan because their pay to play meet and greet was tarnished with the irrelevance of minorities.
Sadly the room, judging by the response, was filed with white people who believed everyone with a certain genetic disposition are meaningless, which is even more dangerous.
So many people seem to forget that the 2008 Hillary campaign regressed into a racist dogwhistle campaign as it became clear Obama was the nominee.
Fuck Usain Bolt in Rio 2016, HRC is gonna be the fastest human in the world when she runs away from progressives after the convention in August. Hoping that appealing to centrists will get her enough votes to overcome the youth and progressives she has dismissed and betrayed so that SHE can become the first female president.
