Whenever I write about this kind of thing I take an opinion on it based on being old and tired, but -- there are actual theorists of interrupting speech who theorized based on practice, including practice that most people would probably agree with (e.g. interrupting speech of actual Nazis before WW II and serious neo-Nazi movements afterwards). It's called "deplatforming" because people would literally overturn speakers' platforms. It's not best characterized by either shouting people down or by stupidly calling for violence. (Some people think that physically overturning platforms is violence etc: it's not the same kind of violence.)
