A stupid, fucking piece of shit who hasn't for even one second taken any formal science classes at an institution for higher education--and is thus, easily influenced by fellow stupid, fucking pieces of shit like Jenny MacArthy--which causes them to be succeptable to scary sounding information even though literally every piece of scientific evidence suggests otherwise.

Someone who is anti - mainstream has a strong dislike of trendy things and people. Many subcultures have preached about being anti - mainstream, most notably punk and heavy metal. Death metal, Black metal, and a few lesser known subgenres of punk rock remain the longest standing anti - mainstream subcultures while others have either become popular (I.e punk) or merged into other more popular subcultures(I.e classic metal and thrash metal). While music subcultures have the biggest anti - mainstream message other subcultures based around religion (I.e LaVeyan Satanism), politics(i.e non partisans), and even literature have emerged. Most trendy things start out anti - mainstream and become popular usually after a slight change in image (I.e in the 1920's united states when white people began playing jazz it became acceptable).
Punk was the first major anti - mainstream subculture, shortly followed by heavy metal and hip - hop.

The converse of an anti-hero (i.e., a protagonist who isn't purely good or heroic), an anti-villain is an antagonist who isn't purely evil nor entirely unsympathetic -- a character who doesn't seem to deserve being cast as the villain, perhaps cast arbitrarily as the villain because they are not the focus of the story but merely present a foil to the central figure, who may be an antihero protagonist. Cf. scapegoat.
Magneto was an anti-villain because, while the X-Men were the protagonists who fought to defeat him and prevailed in the end, we can still respect and appreciate him for his motives and principles, however ill-considered his ruthless methods.
