The way I read it is, "can/should we as a society put limits on others' free speech as it applies to negative/offensive comments about a general group of students (for example students of a certain race, gender, religion, etc.) even when that offensive speech is not meant to personally target an individual?"
Seen another way: even though we have laws that make it illegal to walk up to an individual Martian and yell threatening or insulting anti-Martian things in his face, is it all right (in the interest of keeping society civil and presumably more peaceful) to make laws that prevent us from saying or writing or posting general anti-Martian stuff, like "why don't all the Martians go back to Mars, where they came from?"
Or does the idea of such a law conflict with our generally-held belief in the protection of free speech, even speech that many or most people would find offensive?
Not sure I actually simplified it, and I realize my analogy might be a bit clumsy, but I hope it helped somewhat.
