You mean like his well publicized exercise in Holocaust denial when he contended you couldn't kill Jews with diesel fumes? An ugly canard from Jewhaters on what would be called the right, already debunked when Abu Pat wrote it up in the national media.
Maybe you can answer a question Pat supporters never seem willing to do. What happened to the Christians, diesel fumes being used first on Polish political prisoners. Are they dead or alive? If they're dead, what's this biological immunity Jews have, and where are they?
I was not familiar with that comment by Pat but did a quick Google. Pat did not say Jews could not be killed by diesal fumes but he was skeptical of the figure of 870k Jews at Treblinka were killed in that fashion as claimed as it was a fairly inneffcient was of killing people and would have taken too long??
I would have to see Pat's original comments and article related to this to give you an accurate answer.
