28 April 1967,
American boxer Muhammad Ali refused to attend the Vietnam War. In his press conference he stated that he would not support EE.UU. “against the Vietnamese brothers,” as they never insulted him for being black. He unleashed a real vanity, as in addition to being the champion of his boxing category he was an anti-racism activist. He broke the opposition to the Vietnam war and, in addition to suppressing the heavy weight title, was sentenced to five years in prison. Breaches of resources.
