Replace color of your skin with political belief, and you've just made an argument for Trump supporters who live in places like Berkeley or San Jose to violently defend themselves from liberal rioting.
Find me a leftist actively making plans and pushing for the elimination of those with certain political beliefs, and I'll agree. Saying that people shouldn't be racist or oppose welfare != saying there should be a "peaceful ethnic cleansing", a la Spencer.
