Firm atheist here, but hopefully not a gobby one! Happy to be friends with deists and theists and even have discussions based in their world views as long as it's in the abstract and isn't disguised proselytizing at me.
I did worry that it was an artifact of my JW indoctrination that made me reject all other religions automatically, leaving agnosticism or atheism as the only options. I have done research though and once I learned the model of religion and how it's a means of social control it became obvious (to me) that all religions were man-made.
I did pass through deism and agnosticism on my journey to atheism, but the lack of evidence eventually led me to choose atheism as the only logical position (again, for me).
