On the one hand, when you agree to become a pharmacist you agree to abide by the Service Spec of the Medicines, Ethics and Practice guide, so you could argue that the pharmacist knows exectly what they're getting themselves in for and shouldn't complain...
... on the other hand i do tend to agree that matters unrelated to pharmacy can affect your licence/registration. The Society wouldn't look to kindly on you treating a patient with disdain and isrespect because you disagreed with a part of their private life, and similarly i think this attitude should be taken towards pharmacists.
On the public perception of pharmacists... i think people who know what pharmacists do and have been to them before for advice respect that they are very knowledgable people and can help in a range of health issues, but the majority still see us as no more qualified than the people at argos who get your orders out of the stock room, i put this mainly down to the way pharmacists are reported (or not reported as the case may be) in the media)
