I think the burden of proof should be the other way around. The desire for sex is one of the most fundamental instincts that we have. Who can really say that their first sexual encounters don't stick with them for life? Internet porn is a radical shift in how young people are experiencing sex during important developmental years. Why wouldn't it have a long lasting effect?
No, there have been claims for decades about the harms of pornography. There should be enough evidence for detractors against pornography consumption to use. The burden is proof is on them.
