that first guy is mentally unstable. he was foaming at the mouth for validation from his peers. He is a walking social media disease - substance is irrelevant, being liked and validated is what mattered.
Here is the thing - I just watched the end of the full jubilee video - and some of the other right wingers were open and honest, and took issue with the overt fascism and racism. That was nice to see. But make not mistake - that first guy and a few of the others tell Mehdi to leave - they have friends, they have families, and they are happy to now be that guy. Ergo they are culturally accepted in this country for being that guy. A few months back it was "don't call me a nazi", Elmo isn't a nazi, and...........
I am a nazi and here is my platform of hate.
Applause.
Even for me being the cynic I am , its still shocked me to see kids willing to verbalize violence like this. And it is violence. Opening telling an American citizen to leave "because I don't want you here" is violence.
