Paul, here i swhat the Obama administration said regarding their suit against truck transport companies. Muslim drivers didn't want to transport alcolhol, the companies said that in that case, they couldn't work there, because it's part of the job. From the Obama administration:
"Everyone has a right to observe his or her religious beliefs, and employers don't get to pick and choose which religions and which religious practices they will accommodate. If an employer can reasonably accommodate an employee's religious practice without an undue hardship, then it must do so."
If that applies to Muslim truck drivers, why doesn't it apply to Christian clerks, or Christian bakers?
