This whole thing smacks of the "anyone who has a sexual proclivity I claim not to share must have all sexual proclivities I claim not to share" logic. i.e. the logic that got gay people flagged as child molesters back in the bad old days. And occasionally still today.
Such logic might actually be rooted in projection, which is a deeply disturbing thought. Deeply closeted people desperately clinging to heteronormativity and traditional gender roles because they think that if they don't they they'll do something abhorrent. Maybe even to someone who can't consent. Or they already have and they desperately want to hide away from it.
Yes, for the love of all that's holy and secular too, ban the games with apparent child sexual abuse. Children can't consent. Leave everything else the hell alone.
I don't even play video games with sexual themes, but I do play ones that contain 18+ violence. I assume those will be next on the chopping block.
