Not true. Some states passed it because of the agitprop and the suppressing of the truth in public schools and the promotion of sodomy in all TV and movies.
There should be no “Right” to sodomize anyone since Rights in US law comes from ONLY God-—and the majority votes do not have the right to dehumanize babies and make them commodities and deny them their unalienable right to their biological parents.
Natural Law states that the primary DUTY of a human being —besides self-defense —is to protect their offspring and raise them to be productive, healthy human beings, not sell them to the highest bidder.
Using any human being for selfish lust or to dehumanize them—as the Vice of sodomy does-—can never be promoted in a “Justice” system—since Justice is a Virtue and promoting public Virtue is the only reason for government (Justice).
Not many states have passed it. Those that have generally voted it down until the propaganda machine went full speed.
California voted it down several times and yet they keep finding a corrupt judge to revive it.
So what about straight couples who “sodomize?” Do you want to legislate their bedroom activities, too?
