All of the examples that bclintonk has mentioned seem to me to be violations of the fundamental right to equality under the law.
It is incumbent on all of us to eliminate violations of fundamental rights.
To borrow Hunt’s example: If Thurston Howell VII is driving a Cadillac, that is probably the result of being privileged. Does it raise my hackles, since I drive a Ford? Not really.
At the risk of being supremely boring and repetitive (a boundary I probably crossed a while back), when someone mentions unequal privilege, my immediate reaction is yeah, well . . . When someone mentions unequal rights, I see that as a call to action. I really do not think the concepts should be lumped together, regardless of what you prefer to call them.
