Is it OK to punch a Nazi?

It was a hotly debated question for months after video of white nationalist Richard Spencer getting punched in the middle of an interview on the day of Donald Trump's inauguration went viral and inspired countless remixes.

But the question was never really just about Nazis. It is about the acceptability of political violence. And in the following year the question came up and again and again as several high-profile political protests turn violent, including at UC Berkeley, often considered the birthplace of the free speech movement in the 60s.

We visited Berkeley about a year after that protest-turned-riot to ask students whether punching Nazis, or other deplorables, is ever OK.
