The only apostate thing that I ever encountered prior to waking up was when I was probably 14 or 15 - my friend (similar age) and I were at a door together and the person at the door gave us a little pamphlet that gave lots of information about CTR - talking about how he sold his business and made the equivalent of about a million dollars and sunk it into publishing bible literature and then he started his own stuff. I think there was something in there about miracle wheat and some of the other cons of the time. It all sounded so outrageous to me - we actually read through it with my friend's family after we finished for the day and we all had a good laugh. It just solidified to me that apostates must be conspiracy theorists and are all crazy.
After I woke up I went to one more convention (2014 international convention) as I tried in vain to wake up my wife. That was my first time encountering protesters at a convention, and they were trying to hand out pamphlets and were reading from a bible some scripture about jesus and shouting at us about how it's only through jesus that we can have salvation. I tried (but failed) to catch back up with them on a subsequent day to explain to them that nothing they're doing is helping and give them some better tactics, because it seemed to me that either they couldn't be exJWs or they were so deluded by whatever evangelical group they landed in upon exiting that they thought they could reach people by just shouting bible "truths" at them.
jwleaks and jwfacts were by far the biggest influences on me waking up as far as the actions of apostates goes. Ironically my encounters with apostates had a smaller influence on me than all the rhetoric about apostates. I could accept it when I was told that apostates were bitter/angry/lazy/selfish/etc and that's why they'd left and even that some wanted their own followers, but what always bothered me was when we were told not to take their literature even if they promised to read ours if we read theirs. Obviously if one was the truth and one was lies, it would be clear which was which and we might have a chance to sway this pour lost soul, but no we were told to write them off and run away. That always struck me as hypocritical (which of course we were always cursing hypocrisy in others...) and never sat well. Also a few times I heard my elder father talking about how important it was that apostates not be able to get JW literature (this was about the time that the first watchtower library CD was released) and I just couldn't rationalize why that'd be a problem - shouldn't they be encouraged to have the "spiritual food" that we had? I just couldn't understand the fear that people had about these apostates that were armed only with lies.
