As explicitly spelled out in the Mormon letter this is a solely religious viewpoint. So why would they expect others to respect or obey their edicts? If they choose to do so it's their business. Otherwise this is a matter mostly of rights that are being denied to a segment of the population. Bias and prejudice aside, there is no rational reason that gays be denied the rights afforded straight people. Majority rule does not imply correctness. Have we forgotten the manner in which we denied rights to Blacks? Have we forgotten the way we denied rights to Native Americans? The majority was behind these oppressive measures too.
