I could tell some stories -- funny ones, too. And some not funny.
I guess what makes things cross over the line into intolerable, is the vile crap --- vile crap, not a guy and a gal kaleidoscoping and tumbling in something that looks like lovemaking, but vile crap, aggressively contemptuous of the body ---perverse --- video ---available to every child in a couple of keystrokes, amounting not just to sexual "exposure" as much as an abominable initiation.
It's the ruin of sex, it pleases the slayer of souls. The word that pops into my mind isn't 'liberty'. It's 'millstones'.
I would still much rather live in a culture where people knew what was vile and rejected it of their own free will, rather than have government define it for them.
