Prof. Robin Wilson of the Washington and Lee University School of Law contributes to the SCOTUSblog symposium on marriage:

Very little is to be gained by Professor Singer’s one-hundred-percent-victory-or-none-at-all stance. Where robust exemptions have not been provided, marriage equality efforts have failed. Moreover, under our proposal same-sex couples receive the services they need from individuals in commerce and government employees – by its very terms, in a straight-up contest between religious liberty and marriage equality, religious liberty yields to marriage equality.
