Indeed.
You and Antonio...whatever must add up to a double negative for all the thought you put into this.
Involving "Kiddie-porn" in this argument has long been a conveniant straw-man used by so-called conservatives like yourself (and Falwell/Robertson/FCC) to prop up an argument that you know is destructive to personal liberties in America.
The main difference is, of course, coersion. You conveniantly fail to mention that a child who is forced to perform in porno is not at an age where they are mentally competant to know or truly UNDERSTAND what it is that they are doing. Therefore, they cannot agree to do porno, and anybody who exploits a child in such manners is FORCING that child to do something that they cannot possibly understand or agree to. The actual illegal act is the COERSION intrinsic to the very nature of child porn. There is absolutely NO REASONABLE connection between this conduct and anything practiced by two consenting adult human beings.
None at all, although I'm sure you'll huff and puff and try to tell us that our "being bad" (or demanding our personal freedoms be left alone by the federal jackboots) is contributing to the downfall of Western society, etc., yada, blah... Elvis is evil, Rock is the devil's music, they should bring back segregation, change your diaper...
