"I simply came here wearing a Donald Trump hat. I happen to have it all on tape".
Trump has threatened to deport 11,000,000 people. There are children crying themselves hysterical because they think their families will be torn apart when Trump wins.
There's no such thing as "simply" wearing a Donald Trump hat, anymore than there's such a thing as "simply" wearing a swastika.
Sound extreme? That's probably because you think racism is an innocuous personal procilivity and not an act of violence. All racism is violence. All racist symbols are violent. This guy knew exactly what he was doing and he got exactly what he deserved.
