The First Amendment is forty-five words long and carries five freedoms: religion, speech, press, assembly, and petition. Not one of them is decoration. Each answers something a government had actually done to people.
Religion comes first, and it is two promises, not one. The government may not establish an official religion — this is the wall people mean by “separation of church and state” — and it may not stop you from practicing your own. The model was Virginia. In 1786, after a hard public fight, the state rejected a plan to tax citizens for the support of churches and passed Jefferson’s law declaring that no one can be forced to fund or follow any faith; Madison carried the idea into the First Amendment five years later. The arguments continue — in 1962 the Supreme Court ruled that public schools may not lead students in official prayer, and Americans still contest religion’s place in public life — but the ground rule stands: the government takes no side among faiths, or between faith and none.
Speech and the press were tested immediately. In 1798, with the amendment’s ink barely dry, Congress passed the Sedition Act and jailed newspaper editors for criticizing the president. The law died in disgrace, but it proved why the freedom was written down: governments, given the chance, will silence their critics. In 1971 the government went to court to stop the New York Times from publishing the Pentagon Papers, secret documents about the Vietnam War. The Supreme Court refused to stop the presses.
Assembly is the freedom this course keeps showing you in action. The right of the people “peaceably to assemble” is the legal ground under every mass meeting, march, and picket line: Montgomery’s church gatherings, Birmingham’s children, the quarter million at the March on Washington — and protests today from every political direction. The government may set fair, even-handed rules about time and place; it may not decide which causes get to march.
Now the hard part, said plainly: the First Amendment protects speech you hate. It has to. A freedom that covered only popular opinions would be no freedom at all, because popular opinions need no protection. The real test of the amendment has always been the speaker you would rather silence — and it is also the protection you will want on the day your own view falls out of favor.
Petition rounds out the five: the right to ask your government for change — in writing, at the public hearing, in person. It has been fought over too. In 1836, allies of slavery in Congress passed a “gag rule” ordering anti-slavery petitions tabled unread; the petitions kept arriving by the thousands until, eight years later, the gag broke.
