Adult talk.
@unfa I have reasons to believe my biases for this are way less, as I used to be super religious myself but eventually changed my ways. Most of the anti-porn ideas comes from religion, 2nd (not exactly sure but seems very likely) are from people that feel that it is a demeaning service. If we ignore religion and its ideas of what consitutes morality, we can finally have a good debate around the topic.
If we just go assuming it is bad and evil, there is no discussion possible.
