Milo should not be speaking at universities... getting protested to the point of his speaking engagements getting cancelled is actually a pivotal facet to his whole spiel. He gets paid a shit-ton of money regardless on top of stealing from others under the guise of a college fund (the so-called "Privilege Grant"). Part of me wonders of he's actually disappointed when the protests aren't enough to keep him from carrying out his appearances.
There's a conspiracy going around that he actually put in place paid agitators to turn the protest violent (it was non-violent for HOURS beforehand). I don't actually believe this myself, but it most certainly wouldn't be out of character for him to do so.
¯\_(ツ)_/¯
