My technique is that when responding to any of their posts, I would take Hitlers own words right out of Mein Kampf, and where he wrote "Jews" or "judaism", or any other anti-semetic nonsense, I would replace it with the words "conservative" or "conservatism".
One DUer praised me twice. The first time he wrote: "Well said". The second time he praised me, telling me that I wrote like Bill Clinton!!!!
I managed to get to a little over 100 posts before I was banned.
LOL.:)
