Actually I disagree. I think this is EXACTLY the type of thing the founding fathers had in mind. Have you ever read the federalist papers? The first amendment loses all meaning if it applies to only 'popular' speech. Its the offensive, borderline stuff like Postal that NEED the protection and thats one of the primary reasons it was made to be so broad.
If we only protect the popular stuff we agree with, the stuff without offense or controversey, then whats the point of even having 'free speech' in the first place. Its the stuff society hates which needs the protection.
