Murderers are not a protected minority in secular society.
Homosexuality is.
When you do secular business, secular morality makes the rules.
That’s why there are two distinct questions being conflated here:
- civil rights vis-a-vis anti-discrimination laws
- rights of citizens to avoid being forced to act against their religious beliefs. (The claim is that support of a same-sex wedding is an act that requires them to support something that their religious beliefs prohibit.)
The ‘murderer’ example speaks to the second, not the first, consideration.
Let’s move the example to a bit more concrete consideration, then: let’s suppose that a person wishes a baker to bake a cake celebrating the adulterous affair he’s having. Better yet, let’s suppose that this person is a member of a ‘protected minority’ group. Is the baker’s refusal a refusal against the person of the group, or a refusal to celebrate an event which the baker considers immoral? Would the baker’s willingness to bake for persons in that protected group in the past be evidence that it’s the latter, rather than the former, consideration?
By the way, ‘homosexuality’ isn’t a protected minority. It’s a sexual orientation.
Homosexuals, on the other hand, are protected. They cannot be discriminated against, based on their sexual orientation.
However, the question being asked is whether their
actions – legal, but held to be immoral by some religious communities – must be celebrated by those who disagree with the morality of the actions…
