The apostate is a catch-phrase that is so silly when examined, it makes no sense. I remember when I was young, I was so indoctrinated with this "apostate" ideology that the mere mention of it was something like the devil himself. I remember they used to preach something like a dog eating his own vomit. Such a cult mentality, the seeds of irrationality are planted so early.
There is nothing wrong with questioning any belief, idea or subject matter that you have issues about and just like there are witnesses who sit around all day long and attack other religions, those that they were formerly, that would make them apostates as well, under their own interpretation.
