"I agree they are just blobs of mostly yellow pixels, but you are lying if you tell me that the fact that these pixels are portraying young children has no bearing on the sexual fantasy involved."
What "sexual fantasy"?
If, when you see such images, you see some sort of "sexual fantasy", that says more about you than it does about anyone else.
I think you doth protest too much.
I don't know what the symptoms of repressed paedophilia are, but I suggest you do some homework by finding out. You might find you're in the clear. Or you might find that you've unwittingly revealed to the world that you, yourself, are a repressed paedophile.
Come to think of it, I do seem to vaguely remember reading something, somewhere, about how paedophiles do perceive (non-existent, delusionary) sexuality in images of children (presumably including cartoon children) that the rest of us are oblivious to. I'm wondering if that's the nature of your "sexual fantasy".
Now I'm beginning to wonder if this chronic, growing paedo-hysteria might actually be fuelled by repressed paedophilia. The more it grows, the more it's repressed, and the worse it gets - a vicious circle of self-repression. Might that be the awful truth of it?
