So it seems that even if Obama did miss out on this racist sermon, he attended a racist La Raza conference. La Raza is the racist Mexican-Hispanic group whose motto is ""For La Raza todo. Fuera de La Raza nada," (For those of the race, everything; for those outside the race, nothing.)
Either way Obama was with racists.
Of course, this ignores the 35% of the Mexican population that is purely indigenous, ie not of the "cosmic race."
