How did King's position on the Vietnam War make him less popular with mainstream Americans ?
a. his anti-war stance made him appear unpatriotic
b. his pro-war position angered protesters who supported his civil rights campaign
c. his anti-war stance angered Lyndon Johnson who was a popular President
The best option would be that "a. his anti-war stance made him appear unpatriotic," although the main reason for his stance was that African Americans were being asked to fight for a nation that treated them as second-class citizens.
