When and where did medical science define pornography? Link, please.
Why would it even matter to you ? Didn’t you say there is no authority on pornography?
Seriously ?
How do you suppose medical science could recognize an addiction to something which hasn’t yet been defined ?
This would seem an opportune time to appeal to your um,
authority 
rolleyes
Mine, of course. It is well grounded in the principle of reciprocity, in other words the two variants of the golden rule.
. . .
to emphasize that to date on this thread, you don’t appear to have supplied any links of your own at all so it could be maintained the erratic assertions provided thus far remain unsubstantiated - baseless.
The problem isn’t that no one can define pornography ; the problem is that it has so many different faces , which in turn, makes it complicated/intricate to describe in its entirety .
And you’re totally mistaken in thinking that the appeal it has to different people or to their “tastes” makes it relative and undefineable. The model you present is of inert human beings who are simply subjected to pornography. If that were the case there wouldn’t be much sin involved. It is how a person is going to actively use that porn mentally or physically or both which determines the degree of culpability, which can be mitigated somewhat by addictions ; but hardly ever entirely , since those who are addicted are told there is always a choice
On that last note, the person who is addicted to pornography doesn’t seem to fit into your comfortable little box either. it is no longer a question of taste - it’s beyond their control - hardly something which could be considered morally neutral. And those addicted to pornography are not few in number : According to medical researchers’ clinical data, there are
" millions continue their out-of-control porn use despite consequences of divorce, loss of employment, destroyed reputations, prison time, etc., shouts the obvious: “YES, PORNOGRPAHY IS ADDICTIVE!”
It is how a person is going to actively use that porn mentally or physically or both which determines the degree of culpability, which can be mitigated somewhat by addictions ; but hardly ever entirely , since those who are addicted are told there is always a choice .
I wouldn’t be surprised to discover that I’m not the only one who can’t take your posts on this thread seriously, but just this once, maybe I’ll humour you with a link or two
