Indiana Governor Mike Pence has signed a bill that would allow businesses to refuse service to gay and lesbian patrons on the grounds of "religious freedom", even as some of the state's largest business interests oppose the measure.

Mr Pence, a potential 2016 presidential contender, said he signed the bill because "many people of faith feel their religious liberty is under attack by government action".

Proving that he cannot think, Pence quipped "If I thought it legalised discrimination in any way in Indiana, I would have vetoed it."

And what about religious freedom for atheists, Muslims, ISIS? Can they do whatever they want too, or is this just religious freedom for Christians and Jews?
