I believe that all citizens are entitled to their own religious beliefs only insofar as they do not intrinsically infringe upon the free will actions of other citizens. I suppose that is why I have such an issue with California Proposition 8. You have one set of citizens, predominantly of the Christian faith, who are attempting to legislate their religious moral code upon the entire community of citizens.
We make a gigantic error when we confuse a Constitutionally guaranteed right (a liberty) with the moral category of "rightness" (validity). There is no logical connection between what you have a right to do, and the right thing to do; but there is a psychological temptation to move from one to the other.
"I am the inferior of any man whose rights I trample underfoot." ~ Horace Greeley
