Thanks for that link. As you said a 25 year old of sound mind have every right to decide what she want as per the law. If she goes away from parents or her husband, nobody can dictate her to go back unless she wants to do the same. I feel bad for her parents but we can't overlook her rights too. I would say the same if a muslim girl converts to Hinduism or any other religion.
And, this Markazul Hidaya and many such institutions provinding religious classes to the converts has been there for several years tbh. If the police and NIA finds anything illegal there, it should be brought out to public notice with proofs and should be locked down forever.
Are saying her views are a "little bit extremist" because she asked her parents to convert/ then i am sorry, I have to disagree with you.
Go through the above report and read what her muslim friends said about her initial inclination and association with an extremist couple. Her father also said to have submitted some documents in high court as proof of her association with extremist elements.
