Is there solid proof that the guy was a white supremacist?

A rather despicable act and the right wing better denounce this extremism as much as the left wing needs to denounce ANTIFA's actions.

County sheriff already announced it's being considered as premeditated and officials are pushing for it to be investigated as a domestic terrrorist act.

eye witnesses said he stopped the car a few blocks away before it sped up and crashed into the protesters. They said they find it strange that he suddenly stop because no other cars was blocking him.

Fuck this guy. I do foresee this becoming a bigger problem though. First the regressive left, now the alt right. It was only a matter of time before they reacted violently.

Alt Right is nothing new. It's just a "rebranding" of white supremasists who were here in the 20s, the 30s, the 40s, 50s, the 60s, the 70s, the 80s, the 90s, the 2000s, the 2010s. 

They have been emboldened by Trump's election and think they now have more room to come out of the shadows like coackroaches. 

That's the only thing different today from 10-15 years ago. And they will always be met by resistance now ... because never again in this country's history will they be allowed to parade around in public and to terrorize/bully/expouse their hatred without being met in kind with force.

Alt-Right isn't a thing.  It was an invented word during the primaries to try and paint Trump /His supporters as racists (It didn't work, it's only served to dilute the word and give it no meaning). "Racist" in liberal lingo literally can mean, someone you disagree with.   A vast majority of "hate" crimes that were painted to be labeled against Trump and his supporters have all been proven to be false flags, or outright fabrications. (Just like the sexual charges they claimed to have).  

These protests and the violent turn they are taking is likely the logical outcome/counter response to the well documented accounts of ANTIFA showing up to events with the intent to cause violence for the past two years.  

Hillary Clinton was a crap candidate, that ran on crap platforms, that represented the status quo in one of the most stagnant, and poor performing periods of this countries history.  The Democrats lost at every level politically (Not just the Presidency) because their ideology when met with reality failed.  Nobody cares about David Duke, or the KKK, or "White Supremacy".  

Blaming everything negative that happens on Trump (Which is what I've read from you since the election), is pretty transparent and weak.

While I agree Hilary was a crap candidate, I don't agree with your other points. Alt-Right isn't a "new" thinig, it's just the same ol' brand of racists, I would say though it's a more desperate brand of racism, desperate because the died-in-the-wool racists know they have lost in America and this is basically their death spasm, pinning their hopes on a reality TV buffoon. In 4-8 years they will find there are even more people of color in this country and somehow it isn't 1955 again then what? They will eventually turn on Trump and claim they were betrayed and blah, blah, blah. 

Trump isn't a white supermasist I don't think. He is simply a egomanic/oppurtunist/conman. And in his mind this is a voter block that he doesn't want to piss off, he wants to be able to wink at them in hushed tones. He will probably be forced to have to now specifically condemn white supremasists by name, which is likely internally a disaster for him. That's the last thing he needed this week. "Bad white supremasists, bad. No. No. You can't chew on the shoes, now the Republicans are going to make me have to put you in the back yard and I didn't want that". 

About "losing on every level" the fact of the matter is Democrats have won 5/6 of the last majority votes. That means the majority of Americans do support liberal values in many, many instances. I would say Republicans are fairly lucky that 6/6 of the last presidents haven't all been Democrats (Bush won in 2004 mainly because of 9/11 and Americans not wanting to switch presidents in a war time situation, but if Gore had won in 2000, that would've benefitted him). But that is a seperate discussion. This isn't all about politics, Nazis and KKK should transcend the political spectrum and face condemnation from any person who values any kind of human dignity and has any morality whatsoever. 

That's a convenient way of putting it. What makes you say they won't kill you when way back in the electorial campaigns one tried to light a person's hair during a debate?
