The antonyms for the term "wave makers" can be quite varied and subjective, depending on the context in which the phrase is being used. In general, however, some possible opposites might include "peacekeepers," "mediators," "conciliators," or "peacemakers." These are all terms that imply a desire to soothe tensions or conflicts, rather than stir them up, and suggest a general preference for compromise and collaboration over competition or conflict. Another possible antonym might be "quiet leaders," since this phrase implies a more subtle, less overtly assertive approach to influencing others, rather than the more confrontational or aggressive style associated with wave makers.
