Which is more socially responsible?
Restricting young adults with raging hormones from porn thus
potentially turning them into sex-driven psychopaths or mindless
drones.
Or
Allow the surfing of porn thus reducing the above mentioned
situation but however introducing the potential of brainless fools
who might just watch some porn and decides to rape someone.
I'm guessing jailing a few guys is better than introducing
mindless drones/psychotpaths into the working society thereby
throwing the economy into a dwindling decline.
Wooo... Hold it right there. That's a serious misconception you
got there. Watching porn does not equates to becoming a rapist.
It's a common misconception among the women (yes
the women, I doubt majority of the man thinks that way, they all
watches porn) that believe that watching porn will degrade one's
life and value which is not true and nothing but a myth. Who knows,
it might be women the ones who started this myth. 
I bet majority of the guys on earth watch porn or comes in
contact with it. If what you said is true, you should by now see
the streets full of rapists or what you called "the sex psychopaths
and the mindless drones" but however that's not the case. You are
able to walk on street safely, chatting and laughing about with
your friends in your little world. It's like you are telling me
watching someone smoke will leads you to smoking too or watching an
alcoholic ad will lead you to drinking. Absurd isn't it?
Now you might say watching porn leads men to masturbastion. Then
again there's nothing wrong with that, in fact regular
masturbastion cuts down risk of getting prostate cancer for men.
All right guys you know what to do. It's all for health benefit.

BTW, it is porn that drives the internet and no the other way
round. Now if only I can find the article I read a few years
back.
