Alternative movements seek to modify individuals' behaviors but have no particular interest in revising or reshaping their value systems any more than might be necessary to modify their behaviors. Weight Watchers, the various groups that model themselves on Alcoholics Anonymous, etc., are examples of alternative movements. Often these groups have education components that try to help individuals and those involved with them to recognize when and whether a person needs to make a major behavioral modification. However, they generally do no approach individuals but wait for the individual to seek them out for help. The modus operandi, then, is usually the opposite of that of a redemptive group, which tends to seek out potential converts.
Protest movements are a different kind of social movement from any of the above for two reasons.
First, members are defined by what they are against more than by what they are for. Virtually all of the Contras had once been Sandinistas when the goal of the Sandinistas was to overthrow a government controlled by a dictator named Somoza. When the group succeeded in overthrowing Somoza, it became obvious that different subgroups wanted different kinds of replacements for Somoza and his government, and the most powerful subgroup, retaining the name Sandinistas, imposed what it wanted. Those wanting something else took to the hills and worked together trying to overthrow Sandinista rule. What united the group was its common opposition to something, not a common positive goal.
