Maybe among some people. The rest of us look at crap like 'negging' and see that the whole thing's a tactic to get the emotionally damaged to sleep with the socially stunted.
That said, although I have more or less agreed with you with regards to the 'social stunted' part (as a generalization) 'negging' is not particularly targeted at the emotionally damaged who respond to being put down. It is a tactic charged at the supremely confident, attractive girl who is used to blowing off guys who approach her. The 'neg' is, consequently, first and foremost, an expression of confidence by the person who is approaching her. He is not approaching her as a fawning wretch, but someone who thinks of himself as her equal or even superior.
That this can be a turn on of sorts, esp. when contrasted with the usual types of social interaction encountered by very attractive women at bars and clubs, should be obvious. That the usual types of social interaction at bars and clubs are far from ideal or normative is hopefully also understood.
That initial shock at the lack of deference allowed that person to have more of an interaction than most people got.
Except for the moral aspect, which PUAs seem dead-set on ignoring.
On the other hand, there are entire "systems" that are premised on being dead honest about your intention.
To be more specific if snake oil really did solve the world's problems snake oil salesmen would still be snake oil salesmen. They are trying to get something by convincing others of a thing whether or not it is true.
In pick up artistry, the goal is to be and act like a natural. Sometimes there are a lot of silly hoops on the way and it does not work for everyone, but it does work in the end.
