Privilege Grinch 

1. (n.) Someone who feels they have the right to lecture you on your class, race, or gender privilege even though nobody asked them for their opinion or cares what bullshit they have to say. Highly manipulative, using guilt, shame, and bigoted ideology to accuse others of "privilege crime". See "Social Justice Warrior"

"Suey Park said that white men can't have an opinion on what is or isn't racist because they haven't had the experiences of people of color. She's such a privilege grinch."
