Thing is, Malaysian Muslims, especially the young and ignorant ones.. are too easily strayed off; never ever underestimate the power of words. She has some points in what she's saying, but still most of it are too ridiculous. You should always question everything you came across, but in terms of religion, your questions should be aimed for you to get a better understanding, not to mock or reform it .
I haven't actually read her books, but it seems like she's looking for a reformation in Islam, like she wants to change the religion to suit her, instead of the other way round. Do correct me if I am wrong..
There are some critical questions that she asks which bothers me a lot.. She has apparently question the validity of some Quranic verses, saying that it is confusing and contradicting, as well as saying that prayer's are ridiculous. But then I only read this in a newspaper clipping, never actually right from the book itself, and therefore it could have been altered.
