Ali 就幹過這檔事,
而且還是因為宗教信仰拒絕徵招,
仍然被當作美國英雄.

"In 1964, Ali failed the U.S. Armed Forces qualifying test because his writing and spelling skills were sub-par. However, in early 1966, the tests were revised and Ali was reclassified as 1A.[3] This classification meant he was now eligible for the draft and induction into the U.S. Army. This was especially important because the United States was engaged in the Vietnam War. When notified of this status, he declared that he would refuse to serve in the United States Army and publicly considered himself a conscientious objector.[3] Ali stated that "War is against the teachings of the Holy Qur'an. I'm not trying to dodge the draft. We are not supposed to take part in no wars unless declared by Allah or The Messenger. We don't take part in Christian wars or wars of any unbelievers." Ali also famously said in 1966: "I ain't got no quarrel with them Viet Cong ... They never called me nigger." Rare for a heavyweight boxing champion in those days, Ali spoke at Howard University, where he gave his popular "Black Is Best" speech to 4,000 cheering students and community intellectuals after he was invited to speak at Howard by a Howard sociology professor, Nathan Hare, on behalf of the Black Power Committee, a student protest group.[15][16]

Appearing shortly thereafter for his scheduled induction into the U.S. Armed Forces on April 28, 1967 in Houston, he refused three times to step forward at the call of his name. An officer warned him he was committing a felony punishable by five years in prison and a fine of $10,000. Once more, Ali refused to budge when his name was called. As a result, he was arrested and on the same day the New York State Athletic Commission suspended his boxing license and stripped him of his title. Other boxing commissions followed suit.

At the trial on June 20, 1967, after only 21 minutes of deliberation, the jury found Ali guilty.[3] After a court of appeals upheld the conviction, the case went to the U.S. Supreme Court. During this time, the public began turning against the war and support for Ali began to grow. Ali supported himself by speaking at colleges and universities across the country, where opposition to the war was especially strong. On June 28, 1971, the Supreme Court reversed his conviction for refusing induction by unanimous decision in Clay v. United States.[3]"
