Are the scriptures and literature of the Jehovah’s Witnesses open for interpretation and criticism? Has there been a time where you yourself have questioned the teachings or scriptures? If yes, can you be specific about what you have questioned?
The scriptures and literature of JWs are absolutely NOT open for interpretation and criticism. Criticism, or even just asking questions, is considered rebellious and can lead to your being called an apostate. Apostates are shunned and condemned.
I never questioned the teachings until I had been out of the Watchtower Society for a while. I quit going because I was overwhelmed, worn out and depressed. Once I had some space to think for myself, I realized that I didn't believe any of their doctrines. I'm an atheist -- because of the fossil record and DNA mostly, but also because the whole idea of god seems ridiculous.
I don't know that my answers are very helpful. You might want to contrast our answers with answers from those who are still true believers. Maybe post your questions on some JW facebook page? I think the contrast might be very interesting.
