The Supreme Court ruled Wednesday that a grieving father's pain over mocking protests at his Marine son's funeral must yield to First Amendment protections for free speech. All but one justice sided with a fundamentalist church that has stirred outrage with raucous demonstrations contending God is punishing the military for the nation's tolerance of homosexuality.

The 8-1 decision in favor of the Westboro Baptist Church of Topeka, Kan., was the latest in a line of court rulings that, as Chief Justice John Roberts said in his opinion for the court, protects "even hurtful speech on public issues to ensure that we do not stifle public debate."

The decision ended a lawsuit by Albert Snyder, who sued church members for the emotional pain they caused by showing up at his son Matthew's funeral. As they have at hundreds of other funerals, the Westboro members held signs with provocative messages, including "Thank God for dead soldiers," ''You're Going to Hell," ''God Hates the USA/Thank God for 9/11," and one that combined the U.S. Marine Corps motto, Semper Fi, with a slur against gay men.

Justice Samuel Alito, the lone dissenter, said Snyder wanted only to "bury his son in peace." Instead, Alito said, the protesters "brutally attacked" Matthew Snyder to attract public attention. "Our profound national commitment to free and open debate is not a license for the vicious verbal assault that occurred in this case," he said.
