A veterans' organization has for almost 50 years organized the Boston St. Patrick's Day parade. A group of gay, lesbian, and bisexual descendants of Irish immigrants requested permission to march in the parade. After the parade organizers denied this request, the group obtained a state court order allowing it to march. The state court relied on a Massachusetts statute that prohibits operators of public places from discriminating on the basis of sexual orientation. First Amendment protections attach to parades and persons in them. Gregory v. Chicago, 394 U.S. 111 (1969). One of these protections is that a speaker has the freedom to decide what not to say. Pacific Gas & Elec. C. v. Utilities Comm. of Cal, 475 U.S. 1 (1986).
