So you believe only wedding businesses should get a special carve out? The deeply held beliefs of other businesses don't matter, just weddings?
I think that the imposition to gay couples is small enough while the imposition to the baker (if they are working in good faith with genuine religious conviction and trying to do what they feel is right and in accordance with their religion....which I argue some are) is great enough that I'm inclined on giving a the baker a pass
on this one issue.
As the degree of practical effect on a gay couple that will have to go to another baker doesn't come anywhere within several orders of magnitude of the practical effect of segregation or interracial marriage bans.
I think its a mistake to dismiss anyone who is adverse to making wedding products for gays as an 'anti-gay bigot'. While there are certainly many, I'd argue that there are some that genuinely have no animus toward gays, but are instead motivated by sincere religious belief and an aversion to offending God.
And that their needs are distinct from the bigots....and worthy of consideration.
