As always, we have to thank the pervert ABDLs who go posting around creepy stories and requests (also in unappropriate fora, like in the reported case) and give a bad name to everyone who enjoys wearing diapers although not for a medical need.
There's for sure an enormous difference between doing something for choice, and doing the same thing out of necessity and with no other possible choice. How'd you feel if something as conditioning as incontinence was forced on you? And if, what's more, you found someone with a fetish in your disability that tried to fool you to get you involved in his fantasies? The position of all those angry IC people is perfectly understandable.
Sometimes I wish every DL was given the possibility to choose to become IC by taking incontinence away from someone else who didn't ask for it. I realize this is an irrealistic and probably stupid idea, but this is how I feel when I see someone who lives a life of psychological sufferings and anger because they have to wear something I like. And for how inconvenient it can become, a DL could - imho - cope with it more easily than someone who wasn't given a choice. Probably a choice someone would regret after having done it - but at least they had the possibility to choose.
With that said, it's clear that not every AB/DL is a freaking pervert, this community is a bright example of that, but I also think this is - at least for now - a minority. Some time ago, chatting with another DL, we were discussing the reason why in the majority of the fora dedicated to DLs the conversation showed a substantial lack of level-headedness, and his answer - which made me quite sad - was that simply he didn't expect to find level-headedness in places dedicated to a fetish.
