The estrogen in the water is making the teens hotter. And the nature of social media means that more than ever we're exposed to these hot teens. So they've got to rack up the messaging to be like "um actually it's morally wrong to be attracted to anyone under the age of 25!!" as like an opposing vector because otherwise you might start thinking
>well 17's not so far off 18, really
>and there's no that much difference between 16 and 17, you can drive at 16
>and 15, well that's just 16 rounded to the nearest 5
And this is where it all starts to unravel for modern society, because when you hit the fundamental truth that 15 year olds can be and are hot, that resonates with you, because it's something you know to be true from the marrow of your bones, and you recognise the lie that you've been sold. And then you starts questioning what else might be a collectively accepted lie. And next tyhing you know there's a horde of angry horny hebephile men burning down the courthouse.
