Does the First Amendment protect only the expression of political speech by students but not student speech that is nonsensical (meaning-making no sense)?

The first amendment protects all forms of speech. Restricting any speech even if it's just a single word would mean the freedom of speech is gone. We can see this in China where even talking about how corrupt the government is in the privacy of your own home can get you a one way trip to a "re-education" camp.

your answer is "graduates" hope this

the language of nature was a manifestation from god as he said "let there be light" and there was light the world began to assume visible, comprehensible form.

what ever we know now think of the old vision of creation we can be sure that with out the speaking of word -without language- we would have no science today with its striking power to illuminate the world.
