First of incest is a fetish, not a condition that can be cured, just like you can't cure being homosexual or if you find yourself fancying being wrapped in bubbleplast while going down on a drunk donkey - you might be able to ignore it through therapy but you can't "cure" it.
Secondly please put in link to your scources, when you write a public piece like this where you drag in information from documentaries and studies, then at least tell us where you get the information from.
Lastly, I admire you have the courage to touch on such a sensitive topic and I hope going forward you'll only improve your articles :)
