Brett Kavanaugh: Banning a ‘Class of Arms’ Like Banning a ‘Category of Speech’

[montana]

I understand what you've been saying. But, you're not answering my question regarding the issue raised in the OP: What are "categories" of speech?

Are not libel and slander categories of speech? If they are not, what are?

They are categories of illegal, "acts" of speech. Driving is not a crime in of itself, but the illegal, "act" of driving recklessly is a crime.
