The question is not one of consent. The question is what motivates a person to engage in activity that can or will result in them being ostracized or even imprisoned. Consent of the other party is not part of the decision-making process.
It is a good question.
The United States has one of the highest ages of consent in the world, generally 16 to 18 depending on the state. Many countries have much lower ages of consent. The age of consent in Mexico is 12 for boys and 18 for girls for all types of sexual contact. In Canada, the age of consent for heterosexual sex is 14 and 18 for homosexual sex. See this link for ages of consent around the world.
Organizations like NAMBLA, with the help of the ACLU, are trying to lower the age of consent. The reason for this is simple, legalization is the first step to acceptance. Such as it was with homosexuality. At one time, sodomy was illegal in the USA and most countries. Despite it being legal, people who engaged in it were still social outcasts. Then the maudlin and exagerated tales about families being torn apart because a son or daughter engages in sexually deviant behavior. Skip ahead a generation, now people who express disgust and dismay at homosexual acts are called “bigots”. People who hate people who maintain the moral teachings of the Church are called enlightened and tolerant. While the Church, declaring quite correcty that homosexual activity is wrong yet homosexual people are to be treated with the same dignity and respect as others is labeled homophobic and is the target of attack by those who want to indulge their sexual appetites with no one telling them that there is such a thing as sin.
Such will it be with pedophilia. I give it about 30 years. By that time, to tell a 50 year old man that haveg sex with a 12 year-old boy is wrong will be as socially unacceptable as telling a woman she cannot marry another woman is now.
Unless the Lord returns first.
