Who told you that. Anyway, lets go with that is true (although it isn't), so its oppression because black men who want to date white women (which they do already) want to do so without being criticized.
If criticism, were preventing and breaking ir relationships, that would be one thing but it isn't. Id hardly call that oppression.
Dudes are upset that white women are not paired with black men without anyone saying this and that is what they deem as white women being oppressed.
Well Ill be damned.
