Just to ensure I understand where you are originating your point from, are you saying that allowing pornography to be displayed in the manner that this posts states is justified because we need the test subjects to look into the psychological implications?
I'm sorry but I don't believe you're grasping what I'm saying at all.
Psychologists do not need to generate neuroses on a freelance basis, people are well equipped to produce their own from upbringings where something is considered verboten (talked about excessively, demonized and forbidden) and made into a taboo. Taboos can often lead to extreme behavior in many regards, not just sex, but drugs, alcohol, dating, music, tattoos, piercings, etc. Taboos are fun for kids to break as acts of rebellion but some of the larger ones such as sex can often become neuroses leading to dangerous activities later in life. Most particularly when the person begins to feel guilty for enjoying things he "knows" (i.e. believes) is wrong because of messages imprinted as a youth by his authority figures that "this is wrong, dirty, evil, wicked, etc". Yet his human nature keeps telling him it is perfectly natural to have these desires be they sexual or other forms of
harmless natural amusement. Thus, this person's consciousness is in a constant struggle. This leads to a general unhappiness in life and the eventual acting out such as the destroyed marriages and as you describe, or rapes and worse that I mentioned.
Let me attempt to make this clearer for you, not making something into a taboo does not automatically mean praising it above all other concepts. and not giving age appropriate answers. This extreme jump from one end of the spectrum to the other is part of the prevailing western thought process which is known as "Aristotelian" or "either / or" logic.
Aristotelian logic (developed by Aristotle) states that if something is not completely good, it must be completely evil. If something is not white, it must be black, if you are anti-sex ed and also anti-porn and someone else is pro-sex ed ergo they must want to show pornography to children, etc. Everything in the either / or thought system is divided into stark metaphysical absolutes. This way of thinking leaves no room for learning or intellectual growth and can be the source of much neuroses. Much of the philosophy of everyday life in mixed cultures such as ours, is actually grey area and absolutes may be applicable to some but are not absolutes to others. As far as the gas station in question, if you know about it and have these hangups you always have option of not patronizing that particular station.
Abstinence Only "education" seems to me the effect of an ostrich sticking it's head in the sand believing that since he can't see danger, the danger is gone. I've always said the
best sex education I ever got was when our 10th grade class went on a field trip to the STD clinic for a tour and description / slide show by one of the doctors. Talk about an eye opener!
