You are making a moral equivalence between someone considering the practice and promotion of same sex acts wrong, and a practitioner of same sex acts promoting same.
They are not morally equivalent. One is Wrong with a capital W, and one is Right with a capital R.
What? That makes no sense. I am not making moral equivalence between any two things. What I am saying is that how people choose to lead their personal lives should not be anyone's business. Govt need not promote anything, but it simply cannot discriminate anyone from pursuing things they want to that doesn't harm others.
