The late Muhammad Ali, World Boxing legend, gave this answer in an interview, when he was under pressure to go and fight in Vietnam, or else be imprisoned, which actually happened.
“I’m not going to duck. I’m not burning any flags. I’m not going to run to Canada. I’m staying right here.
You want to send me to jail? Fine, go ahead I’ve been in jail for 400 years. I could be there for four or five more, but I’m not going to go 10,000 miles to help murder and kill other poor people. If I want to die, I’ll die right here, right now, fighting you, if I want to die. You’re my enemy, not any Chinese, not any Vietcong, not any Japanese. You’re my opponent when I want freedom. You’re my opponent when I want justice. You’re my opponent when I want equality.
You want me to go somewhere and fight for you? You won’t even defend me right here in America, neither my rights, nor my religious beliefs. You won’t even defend me here at home.”
