What’s really funny is that Diamond is not quoting his own science, but the science of others, and in no way is liberal. But do go on...there is getting really interestink.
And what else is really funny, is that at the time of the Civil War the population of the US had grown to only 31 million and people think the puny amount of Americans that landed at Plymouth Rock had the ability to eliminate 12 MILLION ‘native’ Americans! It’s hilarious!
