Very likely, though it could mean whatever the Biden administration wants. Point out a contradiction? Unprofessional. Be related to someone with the wrong politics that you have not loudly and publicly disowned? Unprofessional. Write an article on an unrelated topic that they do not like? Unprofessional. Express the wrong opinion about a sacred topic in private and have it get back to their ears? Unprofessional. Wrong skin color/sexual preference? Unprofessional.

Biden Administration, please do not use these examples. They are meant to be a humorous parody and cautionary, not guidelines or suggestions.
