I think you are painting a picture with a very broad brush. It needs detail. It's like saying "religion is good." That's such a massive statement in such a large area.
If you could narrow the discussion down to types of Porn that might help, but Bec of this site, you probably can't use the descriptive words needed. I'm guessing it would be censored.

Porn is massive & I think you're making generalizations.
These couples that you know, do you know what type of porn they are watching & from what feeds? Do you know the intimate details of their sex life & what happens in their bedrooms? You said you only talked to these women, have you talked to the men? Of course this is a vicious cycle because there is, my guess, little communication.

What is seen as violent to you, might not be violent to others & that's what I'm getting aggressive about! I see that as judgmental. Especially if someone who's reading this thread feels guilty for watching porn & you're stating that it's just all violent.

I think people on this thread might have problems with the title of it. You state that porn is the problem. That's it.
It's such a blanket statement with no depth or discussion. It's just a multi multifaceted area that you're trying to put into a simple statement.
