“Religious liberty” as defined by some some in the religious community is like the tragedy of the commons. The tragedy of the commons happened in Europe when a community’s grazing area was owned in common.
With free grazing, each farmer did a private calculation. “It doesn’t cost me anything to add a few cows to my herd.” The tragedy happened when everyone added to their herd and all cattle went hungry.
Today, conservatives point to the tragedy when the topic of welfare comes up. No one will want to work if they can receive money without it, they say.
Liberals point to it when referring to business tax breaks. Each business will want a tax break until no one pays taxes.
Private firms, like Hobby Lobby, use the Religious Liberty to argue it is against the owner’s religious tenets to provide the same benefits to same sex couples it provides heterosexual couples. Other owners do not believe in birth control and want to avoid including it in their employees health insurance.
Somewhere else will be a apartment management firm that does not want to rent to mixed race couples. Another will not like Muslims, and so on.
Some of these religious liberty issues are “commons” issues. They take from the commonly owned pool of standards, money or benefits and want to use it up for themselves.
There are two things in the U. S. we have reached a consensus about, equal opportunity and a level playing field. Religious liberty messes with both.
