I'll most likely get slapped for this but,,,,,,,,, Justica, apart from bleating and ranting on an Expat site where most if not all of the members/readers
live in/want to live in (and I presume this is your country) the Philippines,,,,,, are already partnered "legally"; what are you personally doing to stop the sexual exploitation and abuse of "minors"

? As other members have asked, have you gone to the top? Have you lobbied or are you actively working and badgering the powers that be?
How passionate are you regarding this issue? If you are truly serious and want changes then you need to seek out help, not tirade and point the finger in the wrong direction.
Help is there, there are plenty of NGO's in many countries that deal with this and many other humanitarian issues, if you can't find, ask, if there is nothing that fits the bill, do! I mean do, not whinge and cry.
Set up a trust, not for profit, lobby the right people, seek out volunteers and sponsors, government funding, etc etc.
There will always be those that take advantage of the innocent and weak, remove them and the pickings are slim.
Food, housing, education, then "legal" employment will curtail and hopefully stop abuse of the innocent.
Personally, if I can help, I will, please talk to me/us and let's see if there are any avenues to start the ball rolling on this serious problem.
Facts and figures please.
Cheers, Steve
