The Bald-Faced Lie (boldly declaring the exact opposite is true)

It's just a rhetorical tactic. When the rightful criticism comes it is has already had its sting removed somewhat, and the focus is moved to how the opponent is doing exactly the "unfair" thing which was predicted, and paints the original person as a victim. 

It's similar to poisoning the well but I don't think it's quite the same as it is dealing directly with the point rather than undermining via something irrelevant to the point. 

I believe this might be gaslighting, which isn't a fallacy but is a psychological manipulation tactic based on purposely lying instead of a flaw in their reasoning.
