No U.S. label for domestic terrorists

The U.S. has no legal mechanism to designate domestic groups as 'terrorist organizations'—that list exists only for foreign groups under Immigration and Nationality Act §219. At home, the First Amendment protects association, and officials must charge individuals for specific crimes rather than outlaw group membership. Calls to 'declare' Antifa or others as terrorists are therefore symbolic and unenforceable. — Clarifying this legal boundary reframes how politicians, media, and law enforcement should talk about—and act on—domestic extremism without eroding constitutional rights.
