After years on the internet, I have yet to come up with a pornographic site, simply because it's not what I am looking at.
Now, take my older son!!!!!! Simply because he has so many little brothers and sisters I have parental controls even on his internet site because I have 'stumbled across' what he has been looking at. I'm afraid even 20 year olds can believe that their parents are so stupid that they can't find out what anyone has been doing on the net. So, when we saw what he had been looking it, (which to be honest was soft porn, but then who wants pictures of scary big greased boobs on their computer anyway?) but we decided he needed 'controlling'. Afterall, it's MY computer!
So what I'm saying, is you'll find porn, if you're looking for it and if you go into chat rooms and are daft enough, or young enough, to take everything at face value then you'll probably stumble on some predator or another.
The scare tactics of the WTBTS little 'talks' on thursday evenings, will probably encourage more young ones to go onto sites that are a little dodgy and when they've done that they'll start looking for the kind of real information that the WTBTS don't want them to have.
I've said this before, but I only found JWD because my mum warned me explicitly after a similar thursday meeting to NEVER go onto JW sites. I immeadiately did just that when I go home and then spent about 2-3 months on the net taking in everything about JWs that I could find. I never looked back. It was the best warning the WTBTS could have ever given out. It certainly freed me and my family completely from them.
