I think that's wrong. Speech is sending signals that are converted into information. The difference is, the information can be good or bad depending on what you already have. If we go with the usual Hitler example, Hitler's speech makes people take other people into concentration camps only if they are already inclined into doing it(i.e. if you air the Hitler speech in USA, Americans don't start putting the Jews on trains). Therefore, limiting Hitler's speech is like fighting infection with painkillers when you actually need antibiotics.
