Wasn't racist in the least.

Arguing over technological superiority or lack thereof has absolutely nothing to do with race.

Would it be racist to say that cavemen were primitive because they lacked the steam engine? No, it's merely acknowledging the fact of their state of technology. And it should be noted, primitive in this sense exists on constantly shifting sand: Americans from 1776 were primitive as well. Saying so is not racist.

By our standards today, George Washington was killed by medical malpractice, having been bled to death. It all sounds so barbaric by comparison to what we take for granted now. I'm sure our chemotherapy of today will sound like primitive barbarism tomorrow.
