Ivanka Trump as First Lady in and of itself does not bother me.

16. The fact that it's commonly shared means most people see it the same way as I do

And finding the composition disturbing, isn't "no problem". I have a problem with a picture like this, that's exactly my point. The picture is what's sexualizing a child. Not the viewer.

Justice Potter Stewart famously said this about pornography

I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["hard-core pornography"], and perhaps I could never succeed in intelligibly doing so. But I know it when I see it

the "I know it when I see it" portent can be construed that if many people see something as inherently sexual, then it is by law, just that: sexual.

Also, pretending children aren't sexualized in virtually every form of media imaginable (and that a picture like this doesn't feed into the sexualization I'm referring to) is doing nobody any good, friend. You don't need to sexualize children to see when children are being sexualized.
