Islam doesn’t need reformation because the last message to humanity is complete as it is.I have always said that Islam could do with a reformation, in what areas, I am not sure. However, death threats and family abandonment for choosing to define your own beliefs have got to go. Ex Muslims typically have something to prove to people about Islam, so they often resort to slander, which is obviously disrespectful and wrong. I don't think they are always lashing out against ill-treatment of their person but against the religion as a whole.
Islam and Muslims are two different entities, one is perfect and the other is not.
