Its understood that you're too lazy to actually read the thread but there were few remarks made about this being related to the teens being trump supporters. As has already been linked to and discussed, the hats are seen as a symbol of hate and racism, not just a political advertisement. One of the reasons the Twitter accounts got so popular so quickly is because people we're pointing out where the kids were sneaking in the white power symbol that 4chan made popular.
Now if you're seeing a connection between what the hat has come to mean and your average trump supporter, well, reality can be a bitch some times.
