Well gee, once again he said "I play his attorney". He is not saying these are his positions, he is saying he is taking these positions for the purpose of this thread.
Again.
At this point it is reasonable to conclude, absent looking inside his head, that he might be doing the devil's advocate job or defense attorney job. Maybe. Probably not, because as I pointed out in the "insult post", there are those who were waiting to pounce on anyone who took up the intellectual exercise and accuse them of expressing their actual viewpoints.
humbleman's defense is to acknowledge everything but the holocaust. That is not acting like a defense attorney because defense attorney's are not permitted to disavow actual facts. Which means he is doing a bad job, since he has done nothing to defend Hitler as a defense attorney. Disavowing actual facts is not playing devil's advocate either. Which means he has done nothing as a devil's advocate - which is also a bad job. This is basic reasoning.
Now, humbleman could have used your tongue in cheek comment about Stalin as a defense of Hitler - that Hitler killed fewer communists than Stalin. That would have been a better defense than the no defense of his, because
1) it has a factual basis, and
2) it is based on the reasonable conclusion that fewer deaths of communists is a better outcome than more deaths of communists.
