Which civil right is diminished by someone's offensive speech?
The article uses charlottesville as an example where their actions to guarantee free speech ended up inciting violence and got someone killed. But that's always been the line right and hindsight is 20/20
Of course, the people who make these types of arguments never apply them consistently. I find it incredibly difficult to believe that someone still talking about a car accident in Charlottesville four years ago, while not mentioning the numerous murders, assaults, arsons, and other crimes committed by BLM activists, is someone that is genuinely concerned about "inciting violence".
