Please don't be ridiculous. There are tons of videos you can find on YouTube of leftists shutting down conservative speech. Look at Milo and Ben Shapiro for instance. Can you provide some examples of the right doing the same on university campuses?
Why the ad hominem attack? Show me instances of conservatives shutting down speech like liberals have done with Milo and Ben Shapiro. Even Michael Blomberg has spoken about how liberals have essentially shut down conservatives on university campuses in his Harvard commencement speech.
