not sure i see the conflict, all this comes down to personal responsibility (and personality)
marriages fail for all kinds of reasons, pointing the finger at porn or this or that is a mistake
point the finger at yourself
You can say that about every single thing though. Food, intoxicants, ideologies, everything. I could just as easily say that people just shouldn't fall into identity politics, it's that easy to not get caught in that. But we all know that doesn't work. It is good that there are people who boldly say what the danger is in any subject matter out there.
Sure, personal responsibility is key in everything, but as we all are in more or less fallen state and we all have our troubles, vices, demons and cravings, it's also something to be considered to NOT make traps people can fall into. Responsibility should also go to those who are creating things that are easy for people to fall into.
I think the best way to deal with potentially dangerous things is to remember to blame both parties of the situation. Saying the person who fell down the hole is the only one to blame is wrong. It's also wrong to say the only person who is wrong is the one who dug the whole. Most of the time it's the mixture of the person who made the hole and the person who fell down the hole. So when you are at the bottom, you should always remember that while you are shaking your fist at the sky you should also remember your own part in the whole mess.
It's the age old chain of Adam-Eve-Snake. Adam likes to blame Eve. Eve likes to blame the Serpent, but God says no the whole chain is to blame.
All that said, I'm still part of the chain that promotes and enables pornography. I even wrote my bachelor thesis about porn, and not in the negative sense at all. But as I said before, just because I like it isn't a reason to not try to look at the subjects problems.
But it really is ironic to blame whatever for the destruction of traditional family structure in an attempt to defend porn. Because let's be honest here, it's probably like 1 out of 10,000 if not out of 100,000 porn products that doesn't do the opposite of promoting traditional family structure. If a porn film has a married couple in it, it most certainly has an extramarital affair as its plot line, or there's not that, then the married couple is a lesbian couple (seen that too, lol!). And we all probably react to this with "duh, of course!" which just shows how much we've conditioned to that. Now, sure some would say that there are a lot of married couples doing amateur porn, but as much as there are those, there are tons of more that are the opposite of that.
And again, I'm not saying I don't like porn. I'm just trying to keep it real and honest here.
