In light of Madison's writings, what evidence do you have that the original intent/meaning of the First Amendment was only meant to protect political and religious speech?
If the First Amendment applied to all speech equally, pornography, obscenity (and possibly libel, slander and sedition) would have been protected. And yet they weren't.
In Madison's time, the First Amendment applied only to Congress. Do you accept that James Madison thought that the First Amendment - where it applied - protected licentiousness by the press?
