Ravana Sri Lanka and Sinahalese , neutrality 
He was a Sinhalese. Sri Lankan and  North Indian (Hindi), who wrote orginal Ramayana believes Ravan was Sinhalese ( The Hindu reference). 
As per Sri Lankan myths Ravana is very powerful , Raksha king lived in Sri Lanka who had two children named meganand and other but not mentioned any of Sita or Indian invasion. This page is needed to rewritten in neutral manner. Some Sri Lankan myths says Ravana was very powerful capable ruler and others couldn't fight with Ravana so they wrote a book in which they made him as a antagonist and reverted his real world victories by writing a novel. 
I doesn't mean to remove any of myths written against him. But to mention Ravana's cruelty, raping women stories are taken from the hindu myth story Ramayanaya. Otherwise stating them as real facts will harm the image of a famous Sri Lankan hero. I will put neutrality tag for heavily based on Ramayanaya.
