This document discusses the history and application of free speech protections on college campuses. It outlines landmark Supreme Court cases like Tinker v. Des Moines that established students' right to symbolic speech. More recently, Gerlich v. Leath ruled that students could wear university-trademarked apparel to advocate for legalizing marijuana. While courts broadly protect university student speech, some colleges still try to restrict speech by limiting it to "free speech zones". The document concludes that higher education should cultivate the open exchange of ideas rather than censoring offensive expression.
