Supporting someone like that makes you a supporter of state sanctioned violence against those people and I think every institution -- the media, law enforcement, universities, businesses, etc. -- have a responsibility to denounce this in the strongest possible terms.
This is not simply a disagreement on tax policy, it's about the fundamental human rights of millions of Americans. To see a supporter of this sort of hate receiving softball media treatment or condoned by respected organizations such as YCombinator is disgusting.
