It's easy to look back and give ourselves more credit, as if we were too smart or immune somehow
Honestly, that wouldn't be giving ourselves "credit", it would be admitting that we deep down knew things weren't "true" but were too lazy or scared of making the change and stepping away from it.
I still have a hard time understanding that some people genuinely and thoroughly believe some of the beliefs, because I think there is a substantial number of JWs that attend meetings and either don't know what their beliefs really are or if they do, don't genuinely believe them and are there because of the social aspect and friends and family links.
Anytime I expressed my beliefs as a JW, I felt like a fraud because I didn't really believe them and I thought it sounded stupid. But there I still was.
