50 year old debunked fairy tale. 70's anti-porn Republicans funded a study on porn; the study found it harmless; they pulped the study, and legislated against porn anyway. Reality has never been a friend to conservatism.
It makes sense the right would be fighting against porn as porn is the reason we have the internet. Cat videos are nice, but porn has paid for the pipes. also people seeking porn is the biggest reason we also have ways to subvert censorship and bannings in places like NK and China. Porn is the wind beneath the wings of free speech and information.
I wouldn't agree that excessive porn consumption is harmless, especially to young minds. But if they want to address a public health crisis by restricting a product, they should start with added sugar.
Well for that, Repugs dug up bribe-able quacks to say sugar was good for you. Like they did for cigarettes, and climate change. That was too much money to spend, and too many brains to wash. The porn example shows they just could have said "fuck you, we'll do what we want".
