Let us discuss! Please be reasonable.
I think societey will eventually, yes, treat pedophilia as a form of optional sexuality without heavy discrimination, although I think there will be always at least a small group of people that will directly dislike it. It will become just another form of sexuality because of the tendency of society to lose it's barriers, and the fact that underage sex is already common in most countries, even though it should take some time to a culturally depth to be created. The reason why a antagonic group will exist is simple: the is a anti-pedo culture today. Some will inherit those traits and propagate such antagonization.
But I'm uncertain about one out of the other things. I don't exatcly know or can make a guess about which are going to be the steps that humanity will take in order to become e pedo-normalized society. Maybe something to do with a rupture with the state and other institutions, given that they are becoming more and more alien to people as individuals, giving a feeling that they are distant and apart from what the person is.
Do you think society will eventually accept pedophilia? What would be necessary to be done in order to achieve such a result?
