There will not be many that will stand with God on this issue. Not even many that call their self Christians, for most people including many Christians feels that if you love someone you never tell them something is sin that they enjoy doing & that makes them happy.
There's already republicans that have joined that bandwagon & most Christians who side with the republicans do not realize that the republican party is only Worldly Conservative & not Christian Conservative nor even Christian Liberal.
Besides this country is run by politicians, politics is all about compromising.
Following Jesus is not about compromising, its about denying our self, bearing our cross, & truly following Him.
