1980's: We Are the Monsters.

With the right in control, more and more things were becoming demonized. Hippie movement is damned and everything involved with it, like sex, drugs, and rock'n'roll. Its all that, and of course the occult and satan-worshiping, that is ruining our society, our world, and ruining the chance for Reaganomics to really work.
The very movies you think might try to counter this cultural wave with the greatest tie to occultism, the Horror genre, are some of the movies that pressed this hatred to a new step.
Starting with Psycho (1960), we were given a new perspective on a violent crime. No longer were we watching, unable to participate in the crime, we were involved in the crime. Further more though, we were the attacker. We were in the villains eyes, and we, the audience, were wielding the knife, slashing deep into the showering woman.
Hitchcock may have done that as an experiment, to see how the audience would react and try to give a new spin to cinema, but it took root. Re-emerging later, with Halloween (1978), we are again behind the hockey mask taking part in the murder of individuals. We are the werewolf, vampire, or ghoul stalking behind the bushes, watching our victim, and charging out to get them. Movies like these don't do it randomly though. We aren't put into the eyes of the monster killing innocents. No, we are targeting individuals who deserve death. In The Blob remake (1988) its two drunk college students up on lovers lane, just about to commit the horrific act of...SEX! Other people, like African Americans, drug dealers, rock'n'rollers (who are also doing drugs, and having sex) people who don't listen to their parents are all targetted, all stalked, and WE, the audience, get to be the one to kill them. We get to see through the eyes of the monster attacking.
Of course, the sweet innocent Jamie Lee Curtis won't die though. We might watch her and see her through the monster's eyes, but we'll never get close, we'll never be stabbing her from the monsters perspective. We're given her perspective, a sympathetic one. One we can relate to, and in the end we kill the monster side of ourselves. We destroy the side that condemns those horrendous sinners, the college lovers, even that black drug dealer.

...or do we? The Monster always rises again in the denoument., and so does the hatred and intolerance of such people.
