You are wrong: this is the Government-sanctioned prevention of Free Speech.
The problem is not that there were protesters. The problem was the the Government (which the University is an arm of) allowed a mob to shut down speech, thereby making the Government complicit in the censorship, which is a blatant violation of the First Amendment.
Specifically, the errors made by the University include (1) failing to provide adequate security, thereby permitting fascists to shutdown speech and (2) attempting to require provocative speakers to move their speech to a time when students would be less available to actually listen.
A single unexpected incident is not a problem: stuff happens that you don't plan for. The problem came when they failed to accommodate later speakers.
The blasphemy cited in the article specifically focuses on the government prosecuting and imprisoning those who said the wrong thing. Protesting a speech by someone IS NOT EQUAL to the government imprisoning someone.
A better example of infringement of Freedom of Speech is arresting a reporter that asked a question of the Health and Human Services Secretary. Or prosecuting and convicting someone during Sessions confirmation hearing for laughing out loud.
Just because Ann Coulter couldnt give a speech doesnt mean jack. Isn't it interesting how concerned some people are when one person, who is on the radio and tv and has books published, had trouble giving a speech in Berkeley. However when other people who don't agree with you are actually arrested by the government suddenly free speech doesn't seem so important.
