Free speech is under attack if you are a conservative.  For example, if I say I support Trump in this comment, it will get voted down or censored.

Free speech means that a campus venue should be open to anyone who follows the rules and guidelines laid down, which doesn't include the threat of violence by someone who disagrees with you.

I do not know Levant, but the best recourse against misinformation is an open forum where people can challenge and debate.  This is what a civil society does; a barbaric society uses violence as protest against free speech.

Free speech means you can express your ideas and views while hoping, expecting, and inviting others to challenge and debate you (but not violence)

I hope I helped clear this up for you.
