Also, if you ask him a legitimate question, he gets really defensive.
Matthew Hale, a white supremacist who was found guilty of seeking out someone to murder a federal judge. You can read in depth on the case here. And not only is Greenwald's defense of Hale sickening in and of itself, the trouble he got himself into as his lawyer should really tell you just what kind of person he is.
Racial supremacy is, in my opinion, the height of fascism. As we know, fascism doesn't allow for civil rights for anyone but a certain group of people. How can Mr. Greenwald have the guts to pass himself off as the savoir of our rights as Americans, while defending someone who wants to wipe away and deny rights to entire groups of people? I'm sad to say that he's duped many people on the left into thinking he cares about them or anyone else.
Hopefully this opens many people's eyes to the kind of person Greenwald truly is.
