Also when thinking about hate “speech” - perhaps think of “hateful expression”. Expressing oneself is a freedom I defend whether I agree or disagree. I have “expressed myself” in a way that the one receiving it may consider it “hate” (usually it’s ridicule BUT in text 
it’s hard to tell how messages are received).
Other words for hate are distain, loath, despise - all have nuances of difference - imagine “legally outlawing distain”…
Cranks is from a country that has a sloppy Act and because it’s so slllooooppppyyyy, I agree with his understanding of “hate speech” (as defined in Australia) and would oppose it there.
Here (in my country) I am comfortable with the term “hate speech” because of how high the standard for “hate speech” is in reality, and the way it is defined…(there is a legal boundary: Under section 319(1), everyone who, by communicating statements in a public place, incites hatred against any identifiable group where such incitement is likely to lead to a breach of the peace is guilty of an indictable offence punishable by up to two years’ imprisonment, or of a summary conviction offence.)
Other forms of “expression/speech” (not casual meaning/use) that are not free in Canada under law - Perjury, counselling suicide, and creating child pornography are all forms of expression, but they have been limited through designation in the federal Criminal Code as criminal offences.
Again, these have to be understood in context, and each one of them have been, as Cranks stated, discussed to death. BUT they should be discussed continuously as language usage and generations emerge and societal changes happen.
