I could never support a movement like "Check Your Privilege" because I don't believe in a morality that begins with the unearned... such as any morality which admits original sin.
On the other hand, I could wholeheartedly support a "Check Your Hubris" movement... or a "Check Your Smugness" movement... or a "Check Your Hysteria" movement. Hubris, Smugness, and Hysteria can only be earned (established) through a consistent pattern of behavior.
The times we live in are simultaneously wealthy in things like technological devices and hysteria and yet are impoverished in things like genuine human connection and benevolence. I think the latter two can be reclaimed only with a great deal of disciplined practice.
