Quote: "I seem to remember from my high school civics class that the First Amendment says there will be free exercise of speech and the right of the people to peaceably assemble to exercise this right."

Hmm - Berkeley, Mizzou, Yale, Evergreen, DePaul - etc.  The Leftists are so free speech they try to get everyone who disagrees with them banned by the college and if that doesn't work they forcibly interrupt the presentations.

Free speech is a two way street.  The violent leftist protesters in Chicago, San Jose, Arizona, Portland, etc - bringing bricks and bats and machetes to political demonstrations - all to assault those who have different views.  It doesn't really seem that this is as one-sided as the letter-writer would like to assume.
