Doctors and nurses can't refuse to treat someone because they're offended, but they can drop a patient if they feel that treating them puts themselves in physical danger (i.e. the patient has threatened to harm them physically or has become physically aggressive/violent towards them in the past).  Remember, fats are weak physically and mentally. Something that would cause humans offense would make them feel physically attacked; and some truth that makes us realize our negative flaws would make mature adults feel uncomfortable but convicted/encouraged to work on it, while pointing out a ham's own state of unhealthiness would trigger their PTSD/anorexia/BPD/autism/speshul snowflake cundishun.  Chances are pretty good that the hammy nurses claimed /u/PANTERAisLIFE made them feel unsafe and lied about the things she said to make her seem violent.
