Liberalism is a mental disease!
Actually, it’s more of a moral disease......
Although liberalism is strongly associated with Liberal Mind Fog Disorder (my term), the correlation is not 100%. There are some people who are politically liberal who know exactly what they're doing.
Nifong clearly has some problems, but I don't think LMFD is among them. He's delusional, but not in the way normally associated with Liberal Mind Fog. People with LMFD often have a moral compass that would be correct if their perceptions matched reality. Nifong knows full well that what he's doing is wrong, and has simply convinced himself he can get away with it. His behavior is clearly delusional, but IMHO not symptomatic of LMFD.
