I define know-your-place aggression as the flexible, dynamic array of forces that answer the achievements of marginalized groups such that their success brings aggression as often as praise. Any progress by those who are not straight, white, and male is answered by a backlash of violence—both literal and symbolic, both physical and discursive—that essentially says, know your place!
