The only thing I might want to hold the Christians to is that if they are going to stand on conscience against homosexuality they should also stand on conscience against other sins such as adultery, unmarried couples living together and all that. However there may not be a comparison here either, if it doesn't involve actually being required to validate the adultery etc.
A bakery insisting on proof of virginity for the bride-to-be won't be selling too many wedding cakes in 2014. And probably not that many in 1914.
Cafeteria Christianity, anyone?
"The Christian church, in its attitude toward science, shows the mind of a more or less enlightened man of the Thirteenth Century. It no longer believes that the earth is flat, but it is still convinced that prayer can cure after medicine fails." H L Mencken
