Advocates bring issues into the spotlight. Educators upskill the knowledge of those around them. Organizers focus abstract goals into clear and comprehensible goals, and strategists point those goals toward effective tactics. Backers give the movement credibility and legitimacy and ultimately commit the organization to change. Builders follow through, reformers refine what was made, and when new challenges and inequities arise, so do new movements to change them. Rinse and repeat.
