Who is arguing semantics? Did I attempt to nit pick the language you used? I did not. I said I'd like to hear a greater fleshing out of your position. where were these "mass executions" you're talking about? That's the "fleshing out" of your position that I was referring to. Don't just make generic statements like that, actually explain what you're talking about.
LOL, I see we have another Howard Zinn acolyte who thinks he knows something about real history. That's what I figured was going on. Columbus never at anytime had anything more than 120 to 300 soldiers, maybe. On an island that at most had 60,000 Natives on it. So go ahead and explain to me how exactly the man was able to kill 5 million freaking people. Go ahead, I'll wait. (P.S., destroying Letist Howard Zinn bots like you on the subject of Columbus is one of my personal favorite past times.)
Yes, the Native population in the US was greatly reduced in the century following European arrival. That was in large part due to disease brought to the New World from Europe that killed Natives with zero immunities to them by the thousands and intermarrying with European settlers, even the most Liberal historians will tell you that.
