Drawing the Line

Can you get in trouble for a meme? Could a sarcastic comment land you in court? In the digital age, the lines between free speech and illegal speech are blurrier than ever—and what you post online can have real-world legal consequences. This chapter examines what the First Amendment really protects, breaking down the legal tests courts use and the categories of speech that fall outside those protections, from obscenity and incitement to defamation and blackmail. It also explores how laws differ around the world and why your tweet might be legal in New York but land you in jail abroad. Whether you’re a content creator, activist or just a casual poster, knowing where the law draws the line is more important than ever.
