If this question is “Would you rather everyone be able to talk, or just people who are correct?” Then, uhm, correct according to who?
I prefer having a range of forums of different functions, from “Only my friends can speak” to “everyone, save for those who use speech to harass or intimidate, can speak” to “only the teacher can speak.” None of those fit neatly into either category here (even teachers are sometimes wrong).
