White privilege (or white skin privilege) is the societal privilege that benefits people whom society identifies as white in some countries, beyond what is commonly experienced by non-white people under the same social, political, or economic circumstances. wikipedia 
Privilege seems to be a topic too repulsive to some to discuss, but I find it to be in the realm of things one who is self-aware ought to contemplate. definition
In simplest terms privileges are the meaningful things about which I think little about and yet from which I derive benefit.
To me, therefore, white privilege is all the benefit that I derive by the color of my skin, which is white. Some might want to say they derive no special benefit from their white skin color, but I know that I do primarily because I never have to think about my skin color.
I don't worry about a police officer pulling me over because of the color of my skin. I don't feel suspicion as I walk through a store. I am not frustrated by people not taking me seriously.
Austin Channing Brown writes in "I'm Still Here: Black Dignity In A World Made For Whiteness" what is for me the best summary definition of white privilege I've read so far. Amazon
>White people can be exhausting. Particularly exhausting are white people who don't know they are white, and those who need to be white.
While reading the book I could not help but feel Channing Brown's exhaustion. The absence of that exhausted feeling, that is white privilege.
