Just a thought

The GOP folks who promise to abolish gay marriage seem always to rely on the Bible - Leviticus & Romans, in particular - to justify their objections.
These are, by and large, the same folks who want to introduce legislation prohibiting Sharia law in the U.S.

So, it's okay to foist Christian Bible-based law on the country, but not okay to foist Islamic law on us?
Why does no one ever ask this question of the candidates?
