A reader makes what I think is a very valuable distinction between Muslim cabbies who refuse to transport those with alcohol, and pharmacists who choose not to stock the morning-after pill.

If you get a cabbie license for the airport, there is one less license to give to someone else who will carry drunken slatterns eating pork rinds and their guide dog. If I get a pharmacy license, it doesn’t keep someone else from getting one and opening up a store right next door. So, I can choose to exercise my license or not, without impacting anyone else’s rights.
