“They acknowledged students’ right to freedom of speech, but said that right carries responsibility.”
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof;nor abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
I don’t see any mention of taking care not to offend anyone. That’s an issue of civility wholly untied to the freedom of speech - the difference between oughts and rights. Anyone talking about the “responsibilities of freedom of speech” is merely trying to colorfully veil his objection to someone else’s freedom of speech.
