“There is no sole right answer to “Appropriateness,” especially in terms of dress, mannerisms, and behavior.”
Do you think there should be no standard or criteria for professionalism? If this is the case, how to deal with people who may find certain mannerisms, behaviors or dress offensive, E.G. should a teacher opt to wear a nazi swastika? If there should be a standard, how to make it both inclusive, and not offensive to any sub-group?
