Not quite sure about that.
Surely, you must agree that there are some elements of individual liberty regarding which the majority has no right to legislate.
I suspect that Justice Kennedy (although I disagree with many of his decisions) feels the same way, although he would draw the line differently.
"The case for homosexual sodomy is not weak under the Courts reading of the Constitution it is extraordinarily strong. Hence the argument is very powerful, on logical grounds, for an expansive interpretation of its meaning and scope, which lends support to Muths view that the right should encompass consensual adult incest as well."
Let the black-robed vultures squirm their way out of this one.
