Just to be clear about who is running off ‘tail betwixt the legs’; you challenged and I accepted and you have yet to produce your “expert” who thinks HIV doesn't cause AIDS.
You agreed to take the debate and then backed away. You also backed out of our debate re: Dr. Humphreys/Starlight and Time. And I think you backed out of a third debate, but I can’t recall what it was about. I’ll search the threads to see if I can find it. In short, you are known for backing out of debates with laymen. God only knows what you would do against a real scientist.
