Religious freedom vs. same-sex "marriage."

Would a homosexual owner of a t-shirt printing business be legally bound to print "God hates fags" on a bunch of t-shirts?  Would an American court order a vegetarian photographer to create a documentary video for a slaughterhouse?  Would a Muslim bakery be forced to bake a wedding cake for a homosexual couple?  Are there still people out there that can't discern the difference between race and sexual behavior?
