From The New York Times:
"Not so long ago, of course, government officials invoked religious beliefs to justify all manner of racial segregation and discrimination, including laws banning interracial marriage. The Supreme Court struck down that marriage ban in 1967 in Loving v. Virginia.
It is impossible to imagine any county clerk or judge now claiming a right not to marry an interracial couple based on religious beliefs. And yet, that would be analogous to what these public employees are doing in refusing to serve same-sex couples. The Constitution’s protection of religious freedom simply does not include the right to discriminate against others in the public sphere."
