This is bizarro as hell, pardon my french. I could have expected it to have been overturned on equal protection grounds (i.e. because TX didn't forbid male to female anal sex acts on equal terms) but "privacy"?
Excellent point. I am all for the results of the ruling (yep, consenting adults and all that..), but the "privacy" issue needs to be addressed. When a court can manufacture "rights" out of thin air, there is no end to the mischief that can result.
