Reasons

They make everything.

This guy never said he wanted to see an internet fully of kp/cp. He said he'd RATHER see it than lose his freedoms, the ones that keep society free and unoppressed which are slowly getting taken away.

Honestly, so would I. I imagine I'd probably really dislike the majority of the smut out there if I were to look at it. What's the reason you want to see the internet full of it anyway?

It might actually get me real depressed if it were. Maybe a lot of people think it'd be some thrill or something. I don't know if that means people are sadists or if they're underestimating how awful people can be. Probably a bit of both.

I think for a lot of people it's just that they want to see stuff that makes them sad to make them more empathic and caring when it's so easy not to give a shit about things these days. It's like you don't want to be that normal person who ignores stuff and turns away and only goes looking for things to support their happy world views.
