Free speech myths:
5 commonly believed myths about how US 1st Amendment speech law works

Myth 1: The Expressive Intent or Motive of the Protestor Is the Most Important Factor in Determining Whether His/Her Speech Can Constitutionally Be Prohibited

Myth 2: Laws Regulating the “Time, Place and Manner” of Speech in a Content-Neutral Way Are Unimportant or Are a Pretext for Speech Suppression, and Thus Do Not Really Need to Be Enforced

Myth 3: Expressive Conduct Is Treated No Differently Than Pure Speech Is

Myth 4: The Authorities Could, if They So Chose, Cut Protestors a Break When the Protestors Are Trying to Speak Out on Important Issues to Accomplish Just Results

Myth 5: Even if Rules Have to Be Enforced By Ordinary Governments, University Campuses Are Special Places Where More Expressive Conduct Should Be Permitted

Bolding mine.
