I think the some of the replies to this highlight the issue. I don't think the point of the ads is to blame white people or say there are inferior. The point is to highlight that whiteness has certain privileges attached to it.
I understand that a not all white people are racist and that they were born into the system like everyone else but I don't think that makes it wrong to point out that the system exists. And of course white people expwrience things like poverty and discination. You don't need to feel guilt about being white or even light skinwd but you should be aware of certain issues.
I'm Biracial so it makes me angry when people blames everything on white people
Because I know that my family member and other white friends are not racists or the cause of racism. However that soean't change the fact that in most situations I've experinxed "whiteness" is considered the norm. Also historically white people have had an elevated status and some of that is perpetuates in modern society. Our country has been officially desegregated since 1964. Anti-miscegination laws were made unconstitutional in 1967 (when Obama was 6. His parents marriage would have been illegal in 16 states). That not very distant history.
I'm thinking now of Black hair. Many people chemically alter their hair to be straight or buy very expensive weave. I think the motivation is to fit in with the majority culture white is white. There is an underlying sense that Afro hair (braids, twists,locs) is less professional. Less sexually appealing. Less put together. Or also the use of skin bleaching creams. Or the freaksanomics chapter on how it is a disadvantage To have a very "black name".
I don't think these ads are about tearing down white people. There about recognizing that bias exists in society generally in white people's favor in the united states. If you ignore biases and assume a level playing field you can only conclude that certain groups aren't succeeding because they don't want to (which is sort of an undercurrent in certain extreme right Wing groups. The equally absurd extreme counterpoint being the idea of "white devil"/ "the man keeping us down".
