Free speech law protects offensive speech but not threats or fraud

American courts start from the assumption that speech is protected, then work from a short list of carved-out categories. True threats against a person. Fraud, meaning lying to get someone's money. Defamation, meaning false factual claims that damage a specific person's reputation. Obscenity. And incitement, which the Supreme Court defined narrowly: urging a crowd toward lawbreaking that is likely to happen right then, not general advocacy of violence someday. Being offensive, cruel or wrong does not put speech on that list.

Most arguments about what speech is 'allowed' are really arguments about whether it fits one of these narrow categories.

A constitution is the law that ordinary laws cannot break

Congress passes statutes, and the next Congress can undo them. The Constitution sits a level above that traffic. Article VI calls it the supreme law of the land, which means a statute that conflicts with it is void even if it passed with huge majorities and the public loves it. The document also does the plumbing: it creates Congress, the presidency and the courts, sets terms of office, and lists what each may do. A few thousand words, doing both jobs.

Everything else in constitutional law follows from this one ranking: some rules outrank the winners of the last election.

The First Amendment restrains the government, not your boss

The text opens with "Congress shall make no law," and through the Fourteenth Amendment it now binds state and local government too: police, city councils, public schools, public universities, the DMV. A private employer who fires you over a post, a social platform that deletes it, a private college that disciplines you, none of them are the government, so no free speech claim arises. Other law, like a labor contract or a state statute, might still protect you.

It settles the most common argument people have about censorship, before it starts.

04Ideas

Congress makes laws, the president enforces, judges say what they mean

That split is the whole design, and each branch holds a lever on the others. The president can veto a bill; two-thirds of both chambers can override the veto. The Senate confirms judges and cabinet officers. The House can impeach an official and the Senate removes him with a two-thirds vote. Congress controls the money, so a president cannot spend what was never appropriated. Courts decide what the words mean when someone sues.

Most political fights make sense once you see which branch is reaching into another's job.

05Ideas

Equal protection lets states classify people, but only with a reason

The Fourteenth Amendment, added in 1868 after the Civil War, says no state may deny any person the equal protection of the laws. That has never meant every law treats everyone identically. Laws sort people constantly: driving ages, tax brackets, licensing rules. The question courts ask is whether the sorting is justified, and they demand far more explanation for a line drawn by race than for one drawn by age. Note the word is person, not citizen, so it reaches noncitizens living in the state.

It reframes discrimination claims as a question about the government's reason, not about whether a rule feels unfair.
