Because they’re all federally illegal (until they aren’t) by Lawrence v. Texas. And of those 12, 2 definitely would overturn if Thomas has his way (Lawrence was one of the decisions he said he wants reviewed) and 2 are iffy. Texas would gladly enforce anti sodomy laws today if they could.

I just looked it up to confirm because I've only known it to mean butt sex, but the Wikipedia article on it agrees with you.

I don't think any of those states actually enforce those laws though, most likely because it would be difficult to get evidence of such acts. Just because the law exists in the books doesn't mean it's still upheld, tons of states have "dumb laws" that aren't enforced (you can't keep an alligator in a bath tub, you can't beat your wife with a stick thicker than your thumb, you can't drive on Sundays, etc...) but we're never removed because the process is too arduous.

It's not a solution to the problem they say they're looking to solve. It's more government control, it's big brother, it's everything they say they don't want, so it's obviously exactly what they wanted.
