I'll reconsider not defending free speech from getting a "hate speech" exception when so called "free speech" proponents start talking about getting rid of the copyright exception instead of just wanting to say racist stuff.
It makes complete sense to want to expand the scope of terms that are associated with laws if you don't believe the law is accurate enough. Language evolves through social changes, and so do laws.
