Individuals who are supportive of social justice efforts are not always effective in their anti-oppression efforts. Some who genuinely aspire to act as social justice allies are harmful, ultimately, despite their best intentions, perpetuating the system of oppression they seek to change. Different underlying motivations of those who aspire to be allies can lead to differences in effectiveness, consistency, outcome, and sustainability. The conceptual model presented here, using underlying motivation to frame the different issues and challenges facing those who are aspiring allies, is offered as a tool for student affairs professionals' self-reflection and developing students as allies for social justice.
