I guess those Christians throughout history who have refused to pay taxes (or who have chosen voluntary poverty in order to be exempt from taxation) based on the pacifism that arises from their Christian convictions against war are as "ignorant" of this verse as the atheists.
Christian pacifists opting out of paying their federal taxes, based on the argument that some of those taxes may be allocated for military purposes and therefore violate their religious convictions, has never been recognized as viable by the SC. The exact same conclusion logically follows relative to Christian employers and the purchase of employee health insurance plans that include comprehensive contraceptive coverage.
But because your version of God is cool with war but not cool with IUD's, you are OK with forcing some Christians to violate their consciences and foot the bill for bombs and bullets while not forcing certain other Christians to violate their consciences and foot the bill for MA pills.
Your position isn't based on reason, much less religious liberty. It's based on personal, selective religious bias.
