The court overturned all sodomy laws, not only those aimed at homosexuals. You may say that it is disingenuous to claim that sodomy laws forbidding sodomy in all cases were not aimed at homosexuals, but is it really hard to believe that the same Texans who disapprove of homosexual acts also disapprove of other deviant heterosexual acts?
Private sex acts are surely more private, than abortions effected in hospitals.
Same for incest?
What else is so private that we should not be allowed to restrict it?
Drug abuse? Prostitution? Cannibalism?
Just send a note to Justice Kennedy and ask him. I can't help you.
Actually the Texas law did apply only to homosexuals. LOL. I could say more, but why beat the drum until it has no sound.
