The answer is "unethical communication behavior of reducing others to a single identity".
Communication is great, and accordingly has ethical limits. Communication used to enhance relational relations or to convey moral changes to society is ethical communication. Communication used to undermine connections or support social impropriety is unethical communication. The correct meanings of these rely upon the ethics arrangement of your way of life, yet the vast majority concur that moral correspondence assembles positive connections, while unethical communication disables them.
