Well

Well, yes, you're correct, but it's actually both. But the personal "morality" based upon what one finds gross, icky or irreligious is not supposed to impact legislation or the rights of others to decide for themselves what they find gross, icky or irreligious.

The moral codes upon which government is supposed to be based are those which determine at what point one ceases to exercise one's own personal rights and freedoms and begins to infringe upon the rights and freedoms of others. That is the sole level of morality in which government rightfully has an interest.
