Small yes and big no.

Sure, there is an element of social panic that harms a lot of people in weird ways and may even worsen the trauma of CSA survivors. We need to come to a more balanced view on that particular issue.

But that’s not the primary reason such acts are harmful. Sexual abuse of minors is treated this way because of a simple thing: adults hold systematic power and are in the position of authority over children (which must happen, otherwise parenthood and upbringing will break).

Thus, children do not feel free to reject the interaction, even if they are not directly forced. This leads to inability to predict whether the consent was given in good consciousness or under pressure, and children are normally not interested in sexual exploration outside basic curiosity for anything at all. As a result, they get involved in highly intimate and potentially very gross activity without adequate means and power to reject it immediately, which is potentially deeply traumatic.

As per cultures, there’s a lot of stuff that went on in different places and ages. Greece had pederasty, it also had slavery and complete patriarchy. Japanese culture is very sexually extreme and explores a lot of non-consensual sexual violence, and women are commonly targeted by perverts of all kinds etc. etc.

Just because it was or is active somewhere doesn’t mean we should do it too.
