Is porn really such a big problem in the wt?
I'm from the generation when water was free and you had to pay for porn. Today pornography is a lot more accessible than before. Considering that, I think that the WT and their people are no different than the rest of the people in the planet with Internet access, which means that ease of access might cause an increase in use.
As for people's reaction, don't expect JWs to say "yes, I spend 3 hours a day watching pornography online", or "yes, this is a pervasive problem among us".
It's sad that this and many other religious organizations cause so much sexual dysfunction in people with their inadequate or non-existing sex education.
