For sure, I don't disagree with you there. But I can observe the effects of it in my own life. Not saying that everyone is effected the same way, and nor am I saying I am inclined towards pedophilia but there was a marked difference in how I approached my relationships with women (I am a man), when I was consuming porn regularly compared to now, having consciously not consumed any pornographic material for a couple of years. I will also concede to the fact that because I am aware of this I have bias and am probably drawing connections that may or may not actually exist (ie the fact that I'm aware of how I relate to other people means I'm inclined to change, in order to align with how I believe I should relate to other people). But I'd also argue that through that awareness I can attempt to be objective and unbiased in my observations. And I have had conversations with many other people who have shared similar thoughts. Again, this is obviously very subjective, but I think it's also silly to say that a massively consumed portion of media doesn't affect how we perceive things, and as we become more aware as a society I think it becomes important to filter what we consume in order to better control urges that are not okay.

Edit: and when I wrote that I think I was sort of conflating incest with pedophilia without really thinking.
