You impose inconsequential conditions on them that obviate, for you, their conclusions. That's handy. If a cop tells you not to rob a bank...
It’s not inconsequential and creating a false analogy with a policeman and robbing banks is just tortured logic for contrarian sakes.
The fact is, it’s against the law to rob a bank. It’s not against the law to use birth control so that you can have sex (lets just keep it between husbands and wives) for pleasures sake without having a resulting child.
That is a theological doctrine — nonetheless the government shouldn’t be dictating to the church that it has to dispense birth control from it’s facilities.
