Appeals to human nature are always too facile, and often dangerous. Apple herself contradicts her argument here:

"Yes, there are racists and bigots out there, and it is human nature. It also goes both ways."

If it can go both ways, it's not human nature in the pre-determined sense, the sense that I think you mean (if there is another sense, pray tell). The argument disregards wider, deeper sociological matters. Everything and anything can be attributable to "human nature". A nation's economic prosperity can be down to human nature as much as poverty or racism can be. It's either a truism, meaningless or inaccurate.

'Hate' doesn't come out of a vacuum.
