There is a first amendment right to share your faith. In keeping with that, a bakery could simply print selected scriptures on their cake boxes that point out the unbiblical nature of homosexuality.
If the homosexual “couple” disagreed with the printing on the boxes, well that’s just too bad.
If the homosexual couple disagreed with the printing on the boxes, well thats just too bad.
How is that different from the homosexual couple knowing that the baker doesn't want to make the cake for them in the first place? Your solution doesn't solve the problem.
The issue is how NOT to sell to people who want you to make something that violates your faith, given the recent court rulings and laws in this area.
What I propose solves that problem.
