Saved by grace or not, Selling books or not, disfellowshipping or not, they are a religion that is different than others but they still adhere closely to the bible. They interpret it differently but so does every other religion that believes that the bible is the word of god.
Are there other Christian religions that hurt their members? Yes. Every one of them do it to a certain extent. Pressure to donate funds. Pressure to "hate" wrongdoers. Pressure to "love" others solely on the basis that they are Christian. Covering over the wrongdoing of "elite" members of the church. Protecting molesters through polocies that make people report to the church first. If you think that the JWs are the only ones who do this, you really need to do some more research. Etc. Etc. Etc.
Anyone who follows a groups teachings based on stories thousands of years old is taking their life and putting it in someone elses hands. IMHO.
