The law was invalid and unconstitutional because it allowed heterosexuals to have oral/anal sex, and made it illegal for homosexuals to do.
This is not equal protection of the law.
Equal protection means just that, protection. It has nothing to do with what activities the law condemns. It has everything to do with the government protecting the victims of those crimes by punishing those who victimized them. If crimes against blacks or gays were not investigated, or prosecuted then they don't have equal protection and the feds could step in.
You, like our tyrant judges, have thrown all judicial restraint out the window. There is no way on Earth the Founders / writers of the 14th amendment intended the equal protection clause to enable sodomy. Its absurd. Your insisting that is what it means in no way changes the facts of original intent.
