Use Islam.

Islamic countries are ruled by the majority religion. And look at how women are treated there. One anyone in America say that is moral?

Use History.

It was the majority religion or perhaps the King's religion that most of the pilgrims fled. They came to the US to worship God in their own way. A simple majority doesn't make it right.

Therefore there are concepts such as the sanctity of life and property rights, that transcend religions.
But more specific legalization of religious life is anti-American.
