"Working to protect the rights of some doctors who happen to not want to perform certain procedures"? Let's consider personal integrity for a moment. If a particular procedure is morally repugnant for a doctor, he/she is not FORCED to do it.
Is it greed or fear of losing patients that keeps a doctor from saying "I don't perform 'ZZZ' procedure, let me refer you to someone who does," or putting up a sign in his/her office stating the services he/she provides?
