'Make love, not war' is a slogan that emerged during the 1960s, encapsulating the anti-war sentiment of the time and promoting peace and love as opposed to violence and conflict. This phrase became emblematic of the counterculture movement, which sought to challenge mainstream values, particularly in relation to the Vietnam War. It represented a shift in societal attitudes, emphasizing personal freedom, sexual liberation, and the belief that peaceful coexistence was preferable to military aggression.
