To, the OP, concerning racism, guns, politics, religion.....these are all bad in a pharmacy. Whether or not people want to do them in their own home on their own time is up to them. Actually, I suppose if it's an independent pharmacist owner, then s/he can do whatever they want (within the confines of the law.)
While guns make sense for home defense, in a business situation, they open up a liability, which makes them not worth the risk (which is why most businesses ban their employees from having them.) An example, is that Jerome Ersland who is serving life in prison for killing an armed robber....his murder conviction stems from him going back and firing a fatal shot at the robber, after he had already shot the robber and the robber was disabled on the ground. Ersland knew how to handle a gun, but he didn't understand the rules about when it was legal to shoot (or because he was a pharmacist and not a police officer, he panicked in the heat of the moment.) He was an independent pharmacy owner, so it was his own business to lose, but chains (or hospitals) don't want employees like that opening them up to a massive wrongful death lawsuit.
