The overwhelming majority of recorded cases of child abuse in Pakistan happen at home i.e. at the hand of relatives and in seminaries so the theory about trafficking and poverty seems like a misguided attempt to link two unrelated issues. That's not to say trafficking doesn't exist, I should know living 20 odd miles from one of the larger hubs of child prostitution in the Pindi-Islamabad region, but it's not the main cause by any stretch of the imagination.
Bachay bazi is simply a name given in KPK to what is a common practice across Pakistan though I don't see how you figure that the people there revel in it considering that you, by your own admission, are fairly ignorant about the nitty gritty of Pakistani society and are unlikely to know something like that one way or the other. I was forced to correct one poster who made claims similar to what you're insinuating, that it is largely restricted to KPK or part of the culture there which is patently not true as anyone living in Pakistan can confirm for you.
It shouldn't be too much of a surprise that I brought up the role Islam has played in shaping the less savory aspects of our culture considering I'm one of maybe three people here who are both Pakistani (not including BritPaks) and not completely enamored with all things Islam so in any given thread concerning social issues here, it shouldn't be too much of a surprise if I'm the one who goes against the popular line and explores the role Islam may have played because the common theme here in sight issues is to deflect blame elsewhere as is the case in the Raymond Davis thread where a poster tried to blame the blood money laws on our corrupt leaders when those laws are, plain and simple, Islamic laws in a country where ~80% of the population supports Islamic law until it bites them in the rear end.
As far as the clergy goes, the less said the better. The official policy is one of silence, or half-hearted condemnation if really pushed on a public platform but the clergy, as a whole, also happens to be the single largest perpetrators of sex crimes against children. Religious seminaries across the country are notorious for this kind of thing with many of them run by religious organizations that enjoy a great deal of political power. There was a case a few years ago where a Jamat e Islami run seminary made the news for an untoward incident which was swiftly brushed under the carpet and no action was taken. That, btw, is par for the course for Pakistan.
The vast majority of reported child abuse cases happen at the hands of relatives in ALL countries. Not just in Pakistan. You would do well to educate yourself on child abuse statistics around the world before making sensational statements that seem to portray Pakistani society as the worst offender. Especially, when after several lengthy posts where you have produced zero facts to strengthen your argument.
There definitely have been instances of where teachers at madrassas have sexually abused children - the same has happened at regular schools and colleges despite your denials - but that only proves something that everyone knows: bad people can be found everywhere. What this does not prove however, is the undeniable link between Islam and the sexual abuse of children. Like I said before, the punishment for illicit sexual relations in Islam are severe and there is no religious scholar, nay, even a regular Muslim who will state that cultural practices like "baccha bazi" have a place in Islam. If such people do exist, they are truly ignorant.
Thus, child abuse, whether physical or sexual, has zero basis in Islam. Some Muslims may and do engage in deviant practices but so do some Christian, Jews, Hindus, Atheists, Communists, Democrats, Liberals, PETA and every other group of people out there. As long as the group as a whole does not stand for something, it is naive to blame it as a whole for the actions of a minority of its members.
Your claim that Islam's rulings on the segregation of men and women cause Muslims to develop deviant sexual urges is yey another uninformed statement. Like I said before, do brush up on your knowledge of child abuse practices in places like the US, UK, Australia and South Africa, where men and women mix freely, and then claim that Islam is the cause.
You may be a unique snowflake who happens to live in Pakistan and denounces Islam but that does not mean you get a free pass on posting faulty "information" and we should believe every word you say.
Poverty, corruption, illiteratecy, drugs and culture are the reasons why so many children in Pakistan suffer. Not Islam.
