Whether porn is harmful to people or not really doesn't matter.
Lots of things are harmful to people that are still legal. Tobacco, Alcohol, Fast Food, Internal combustion engines etc etc ad infinitum.
Bottom line is that adult erotica is protected speech and if you don't like it, there's nobody out there forcing you to look at it.
If you're pissed off that your husband is looking at it.....well if it weren't for internet porn he'd probably be downtown picking up a hooker.
