Facists aren't a Protected Class. Most common targets of Facists are.
Being willing and ready to protect those who by law deserve special protection against those who don't is, in my opinion, praiseworthy.
As I said in the "Trump 11" thread, there's a key factor here:
The reason fascists aren't a "protected class" is that they can always just stop being organized fascists. The people they target, usually don't have a choice. Jews under Hitler's reign couldn't just say "I renounce Judaism" and be okay. Many people that were lynched in the US were just black people who were just...around (and yeah, I'm counting that as a form of fascism). A lot of people deported in "Operation Wetback" were born US citizens. There's an essential difference between targeting people for what they
do, and targeting them for what they are.
Richard Spencer could have sat around all day snarling at every ad that showed a white woman next to a black man, and I wouldn't care less. But since he decided to organize a violent hate movement, he someone ran up and punched him in the entire face, and I watched it repeatedly and laughed every time. And I'll say the same for Gavin McGinnis, and I'd laugh out loud if he got punched in the face like Spencer did. I'm not saying we suspend laws to allow anyone to do so - but really, that guy should be up on federal charges.
Also, from what I see, a lot of Antifa activity is just figuring out who various nazis on Twitter/Gab/"other platforms" are, and reporting them to their family and employers. Still retributive, but not violent.
