Problems with numbers

It is amazing to listen to how innumerate the average person is. You can easily see this in Skypeland. One person claimed that the indigenous peoples had lived in the Americas for 27,000 years. I told him he was incorrect, and he disagreed. I asked if he had references for this and of course he claimed he did. I asked for them, and he said he would send them. He promised several times, but of course I never received them. I went looking and confirmed that the standard accepted age is 13,000 years ago, but recent discoveries might push this back to an astounding 50,000 years ago if confirmed:

Then one of our classic visitors to Skypeland is a bit of a dufus. He claimed that the war in Iraq was almost as bad as Vietnam if not worse in terms of deaths. He also claimed that the death toll of American soldiers in the war in Iraq was worse than the death toll of American soldiers in World War II. I tried to dispute him, but he argued against me with ludicrous reasoning and crazy numbers.

I looked, and the US military death toll in World War II was 407,300:

The US military death toll in Vietnam was 58,200 and 305,000 injured:

The US military death toll in Iraq to this point is 3795 and 27,180 injured:

This person had claimed that the 27,180 injured in the Iraq war makes the casualty rates in Iraq much worse than the death toll in Vietnam since there are now better medical techniques available for keeping people alive. Hmm....sounds basically clueless...
