I really didn't want to participate in this argument, but I have to call you on this. The constitution only protects your rights to free speech from intrustion by state and local governments. You still have the right to speak your mind without fear of getting in trouble with a government, but whether people choose to be offended by your remarks is utterly unregulated by the constitution, and shouldn't be. After all if the government said that you couldn't be offended by remarks that somebody else made, wouldn't they really be stepping on your own rights to free speech?
Gun laws, I see your point, but your political correctness infringing on free speech rights argument is a total non-starter in my book.
