We are all members of one human family, the species Homo Sapiens. We are all decedents of the same Odd Little Primate that emerged from the African continent in the distant past. We share the same genetic code with all ethnicities, nationalities, and religious groups. Separate is not equal. Tolerance of those you perceive to be different than yourself is good.
Ignorance is Bad.
Growth of the species can only happen if the current generation is able to stand on the shoulders of the preceding one. We can learn from our ancestors mistakes. Only by learning can we progress. We must learn in order to survive. We must also teach.
