Simple solution. Don’t use currency.
Atheists and agnostics and whatevers can use credit cards. I’ve yet to see “in God We trust” on any credit card.
They can have a special atheist credit card imprinted with "There is no God to trust".
The agnostic credit card can say "I'm not sure who or what to trust. I'm just not sure."
They may also move to a country that doesn’t offend them and use their money.
When can we explaine to these a$$holes that the constitution doesn’t extend the right to not be offended.
