broadly speaking, hate speech is free speech - the exception coming when somebody is being directly threatened.
but, if we're talking about speech rights, the most important speech right is the right to protest; without the right to protest, there is no meaningful right to free speech.
conversely, nowhere does the right to speak imply the right to be heard.
this is a part of the reason i don't get into this. when you have a group of kids outside yelling that a speaker should be shut down, it is their right to yell that is protected under speech legislation - not the right for the speaker to speak without being interrupted. there is no right for such a thing anywhere, in any law, in any country. all concepts of free speech in this scenario apply exclusively to the protestors.
if the system passes a law that says that people can only speak during certain times, this is a violation of speech rights, and should be challenged under s.2.
