[Kulturkampf]

I would point to societies, such as the Greeks, where even a degree of homosexuality was practiced or such as the Afghans, who though practiced pedastery (sp?), never thought it acceptable that their homosexuality would be an attraction to other adult men.

Even in societies that had no gender construct that would inherently pressure someone to be a heterosexual and even where havign sex with boys was acceptable, it eventually was viewed that a literal practice of homosexuality between two men acting as grown-up lovers was taboo.

Basically, in every society except a few where fucking young boys was cool, homosexuality has been viewed as not an acceptable way of life. It is not a natural form to the human.
