who's a traitor?
The whole point of those protesters is that they are racists. What aggravates them is a nation which has less tolerance for racism. They hate the idea that anyone besides themselves get to be free. But in doing so they have to fight for politics and policies which make the nation a poorer, weaker, less safe, and less free place. In short, they are fighting to undermine the nation itself in order to pursue their goal of having a preferential place in the nation over others. They call themselves patriots and wave the flag a lot. But their actions harm the nation. And they are doing so in a great deal of a similar way to the Confederate traitors who started the Civil War.
