It's more so a rise in anti-bullstuff
Nationalism isn't anti-bullstuff. It's simply pride in your country and your culture. As with any narcissistic tendency, putting yourself above others causes you to desensitize yourself to them, and when something horrible happens to other people, you stop caring and possibly egg it on to continue.
Armenian Genocide, Holocaust, Rwandan Genocide, they all start with nationalism going out of hand. CIA is another case of how nationalism and politics results in a dangerous group that terrorizes others who are not them.
I don't think that every Annoying Orange supporter is a tribal whitey who hates everyone else, but Annoying Orange definitely brought some of the more lowkey nationalistic groups back up to the surface. Either way it's not worth debating anymore, he's president and we all have to respect that. He was elected fair and square and people who complain are just wasting their time.
