For an example of what he is talking about, the Native Americans got overwhelmed and their cultures driven to the point of extinction simply because the European settlers outnumbered them.
You don't know anything about European colonial history do you?
Because it wasn't sheer numbers that did the Native Americans in.
I'm not talking about the early colonial era, I'm talking about what happened when we, the descendants of the European settlers, started kicking them off their land and shoved them onto reservations for them and their culture to wither and die. Look who outnumbers who, and look who has a culture in danger of being overwhelmed. Indian casinos certainly aren't part of their original culture.
That IS the early colonial era. Native peoples were screwed basically almost as soon as we came ashore.
It is hard to put an exact figure on it since Native Americans didn't exactly fill out a census form of their own, but most historians agree that native tribes lost 60%-90% of their people from disease alone.
The Great Plains Indians did not lose their land and sit on reservations because we outnumbered them in the plains, we didn't.
At the time before whites showed up, North and South America had a native population that ran in the hundreds of millions, cities in the 10s of thousands.
We didn't need to kill them or out culture them numerically. By the time whites moved into an area in sufficient numbers to be a force as a culture, the damage was already done. The Plains Indians were not overwhelmed either, we chased them down with guns and forced them to sit in time out and then they got sick and died like all the rest.
The Plains Indians couldn't have functioned if we had a greater cultural impact on the land than they did.
