I don't know why you bothered to post. You don't seem to have much of a clue what "neoconism" is.
I would be mildly shocked if 10% of leftists have a clear idea of what neoconservatism is. I did an internet search, looking for an honest, objective explanation of neoconservatism, and found page after page of wall-eyed leftist ideologue anti-neocon harangues. Obviously the hard left is spamming the net and using "neocons" as convenient scapegoats and whipping-boys. The average leftie, loathe to look at any information that doesn't come from a fellow traveller, would be completely taken in and utterly disinformed.
It took a while to dig through all the lefto-spam, but I eventually found this:

Leftist readers will quickly see that a good deal of careful cherry-picking (or simple, stubborn denialism) will be required to absolve JFK, Obama, and even Clinton from the loathesome stigma.
Oh, the horror.

They
are neocons.
