It seems to me the choice of examples is intended to show Facebook is racist. But in my opinion it fails to do so. Their rules may be stupid, but if applied consistently they are not racist.
Example: White men is protected, but Black Children is not. Ok. Question. Is Black men protected? I assume so, if I understand the Facebook rules correctly. Is White children protected? Again, if I understand the Facebook rules correctly, then the answer is no.
So what do we have: white children. Not protected. black children, not protected. white men: protected. black men: protected.
Then the sex discrimination that is implied: apparently female drivers is not protected, while white men is. Fine. But the question is: Is 'white females' protected? If I understand the rules correctly, yes it is. Is mMale drivers protected? If I understand the rules correctly, it isn't.
So what do we have: white males protected, as is white females (and consequently, also black females). female drivers not protected, male drivers not protected.
So based in the information I see, you cannot conclude that Facebook's rules are either racist or sexist. They are stupid as fuck, but not racist or sexist.
