All speech should be presumed to be protected by the Constitution, and a heavy burden should be placed on those who would censor to demonstrate with relative certainty that the speech at issue, if not censored, would lead to irremediable and immediate serious harm.
We don't have an Official Secrets Act in the United States, as other countries do. Under the First Amendment, freedom of the press, freedom of speech, and freedom of association are more important than protecting secrets.
Being offended by freedom of speech should never be regarded as a justification for violence.
Censorship laws are blunt instruments, not sharp scalpels. Once enacted, they are easily misapplied to merely unpopular or only marginally dangerous speech.
