Following that logic then, those patriots who didn't miss that important point are not "birthers".
I take the term to mean those who believe that he is ineligible BECAUSE he was born in Kenya. These are the ones I believe have missed the point.
If you want to include those who believe he is ineligible because he was born in America and his father was not a US Citizen, thus he is not "Natural Born", then my comment regarding "Birther's" would exclude the second group.
