They got lei’d.
Noting that gay relationships are not a constitutionally enumerated protection, Section 1 of 14A prohibits state laws which abridge true constitutionally protected rights, the 1A protected right of religious expression in this case.
And for liberals who argue that the Equal Protections Clause of Section 1 of 14A protects gays from being refused services such as B&B, note that Section 2 of 14A discriminates on the basis of sex, age and citizeship regardless of the Equal Protections Clause. So states can make laws which discriminate on bases not expressly protected by the Constitution, as long as the states discriminate equally on such bases.
