In my experience, the people who insist that there is no such thing as being apolitical are the ones most averse to political views different from their own. More often than not, people who insist that coworkers should bring politics into the office neglect to consider that many of their coworkers probably hold views they consider morally wrong or harmful. For instance, several co-workers who made such statements had also called all Trump supporters white supremacists (attributing the label to all supporters was explicit) and that apprehending any illegal migrants at the border is inherently racist. Something tell me these people have a pretty specific image in mind when they're encouraging their co-workers not to be apolitical in the workplace.
