what exactly are you trying to refute?
Bush's father had some shady connections to Nazi-related businesses in germany.
In addition, IBM sold punch-card tabulation machines to the Nazi party which they later used to catalog jews and other "unneccessary people" in their concentration camps.
I wouldnt try and refute it. Giving the author of the piece any time is only strengthening his position.
Really? any source for your accusation?
