I would be considered among those of the religious persuasion, just so we are clear.
There are plenty of elected officials that think with their (religious?) upbringing.
Do I have some (religious?) superiority in terms of the secular rights I have because I married a female? Do the life-long commitments of same sex partners deserve any less consideration? There is probably very little, if any, evidence that heterosexual marriage lasts any longer than homosexual. So the basis can only be the (religious?) upbringing of those elected officals.
