"Our First Amendment expresses
a far different calculus for regulating speech
than for regulating nonexpressive conduct
and that is as it should be.
The right to swing your fist should end at the tip of my nose,
but your right to express your ideas
should not necessarily end at the lobes of my ears."
-- Alan Dershowitz- Professor of Law at Harvard Law School
