I want you to re-read what you just said, and think of things from my perspective. Imagine if someone came along, and said this thing you enjoyed was wrong, or evil, and should be suppressed/abolished; and then, when you tried to defend it from what you saw as unjust accusations, they simply brushed your objections aside as "well, he's just addicted to it, we can safely ignore anything he has to say."
I suggest you look up argumentum ad hominem, because that's what you just did.
No it isn't. The focus of discussion there was not whether pornography is wrong, but whether it is addictive. Which is not the same concept.
Now what is the essential feature of addiction? Is it not that certainty on the part of the addict, that this is something that he or she cannot live without, and would sooner die than give up?
Of course I understand that one cannot cure people of an addiction merely by telling them that the thing they are addicted to is wrong, or even by declaring their addiction illegal. Don't confuse me with TNoL.
