Cantwell personifies the so-called white nationalists: for all their political pretensions, always the same stupid faces, the same goons playing their Nazi games, strutting around with their shiny firearms and yelling their inane slogans. For all their tough guy posing, just little boys who never grow up -- reduced to silence, or to tears as Cantwell was, by mature and responsible citizens who know much better. 
And those fascist juveniles voted for Trump, and praise him still, though his apologists might like to pretend otherwise.
