I see your point but I am afraid that you are wrong about the fact that there are no larger groups like them. People are scared to say they voted for Trump, not because of this violent attack but because of the kind of rhetoric that preceded it. "Trump is Hitler" is a phrase I hear regularly at my university. What does that make me and my family? Being told that my family is made up of Nazis is infuriating. Watching people do these violent attacks to my group is threatening. My fear is that the violence is a result of the rhetoric, and this is not an isolated incident either. Eggs thrown at a woman who voted Trump. Man who voted for Trump was beaten up, video recorded, annoying woman screaming "Fuck Trump" just like in this case. I can give you links, but I'm sure you can find it with a quick search. I am not saying this as a fact, but I have this uneasy feeling that these attacks represent a larger group of people. No one should be afraid to say that they support the President of the United States, and this kind of crime does exactly that.
