Femtography It's a fair question. The crackpottery of the OP lies not in its incoherence. Plenty of normals skip steps in their explanations. The problem lies in the inability to accept that failure and in defending the irrational as if it were rational.
Your examples were not necessarily all examples of crackpots, but were instead a listing of those conclusions you simply disagreed with. It therefore appeared simply as an arrogant display of personal rightness, and not as a true analysis of crackpottery. I tell you this because you noted you wished to self-evaluate.
I'd place conspiracy theorists, anti-scientists, and half-brains under the crackpot umbrella. A half-brain is a Hanoverian term that describes someone who has mastered academic lingo but only halfway understands what they mean. This person lures a full brain into a conversation that quickly ends in disappointment when the half brain says something revealing.
A crackpot example: I recall a long conversation I had once with a poster who insisted that American jurisprudence was doomed from its inception due to its adherence to the philosophy of J.S. Mill. Not only did he misinterpret Mill, he didn't view the fact that Mill was born after the Constitution was long since written and signed as problematic to his position.
If you get drawn in and pissed off, you are dealing with a crakpot extraordinaire as they say in France. The PoMo movement is healthy in France by the way.
