> You don't think the millions of hours of widely available online porno has any impact on our culture or how people view sex?

No, hence why I didn't say that.

> It's incredibly ignorant to think that "evangelical Christians" are the only ones opposed to porn

Lots of people are opposed to porn. The idea of porn addiction, OTOH, is very strongly associated with religiosity in general, and certain socially consevative Christian subcultures in particular.

Being opposed to a thing and thinking that association with it fits in an addiction model aren't the same thing.
