I agree it should be upheld. But for only one reason. The US constitution does not prohibit states from passing sodomy laws.
The sodomy statute would be upheld ONLY if the Court is willing to extend the highly imaginative Roe vs Wade right to 'privacy' to sodomy. There was never any constitutional basis for Roe vs Wade. There is none for the sodomy laws.
Sodomy laws may violate the 14th Amendment.Roe Vs Wade is not relevant to this issue because abortion should have remained a state rights matter.
