text: That depends on your meaning;\n\nAs comedy through the ages and more often comedians of this age have shown us, mocking others is the core of how they make their living.  However, most nowadays preface their comments or follow-up by saying they really like "focus of joke".\n\nHOWEVER, if you are doing it as an intentional insult, to specifically draw attention to a person or group for the purposes of systematically and sincerely belittle them and portray them as smaller or less important than yourself, then you are totally in violation of any and all ethical conduct as we know it in modern western society.  In this way it would be rude and insulting.\n\nJust my personal opinion.
