Yeah, Clemson should never invite speakers that left-wingers don't like. Because we all know that things like a "nine-day sit-in at Clemson's administrative offices" always bring the campus together.
Milo is a conservative provocateur who is really good at rustling left-wing jimmies because he is willing to criticize feminism and other liberal shibboleths. He also has basically an anti-liberal comedy shtick, which, like all comedy, is partly serious but largely a gross exaggeration. But nothing he says is so objectionable that he shouldn't be allowed to speak on college campuses, and liberal groups have embarrassed themselves with their antics at other places where he spoke. It was especially ridiculous at DePaul, where BLM-affiliated protestors stormed the stage, violently grabbed the mic from the moderator, screamed in Milo's face, threatened him, and took a swing at him. The school made the sponsoring group pay extra for security, but then told the security not to do anything. So the event had to be cancelled after Milo only spoke for about 5 minutes. Here's footage:
As for the whole "Make Clemson Great Again" thing, it's an allusion to Milo's support for Trump. I don't agree with him there, but he's not saying that there's anything in particular that's wrong with Clemson (although he's been very strong with his criticism of the way speech is suppressed on college campuses, and the way feminism has played a key role in that trend).
