It would seem that the art of insulting people and character assassination has gone downhill in recent years with nowhere near the elegance and power that it has had in the past. This great art is a pale shadow of its former greatness, at least here in the West.
This decline may or may not be of practical importance depending on what field you are in, as some fields make more use of the insult and verbal backstabbing than others. The culturally important field of visual effects and animation is known throughout the world for the shallow insults members of the field shower on each other. Only paleontology is believed to be more verbally vicious and cutthroat.
One esteemed style of insult, one of the greatest in history, was created during the Cold War by the various Communist governments. Although almost all the former practitioners of this style have abandoned their own traditions in their haste to embrace capitalism, one country has stood firm and maintained its traditions. And that country is none other than the proud but misunderstood nation of the Democratic People's Republic of Korea (DPRK) as led by their Dear Leader Kim Sung-un.
Just recently I came across a fine example of this art when I read about the purge of Kim Sung-un's uncle, Jang Song-thaek, formerly the second most powerful person in the DPRK. Tears came to my eyes as I read the announcement of Jang's execution so struck was I by the sincerity and venom of the text.
1. But keep in mind, if attempting to apply these techniques of rhetoric to the field of visual effects, that many of the practioners in the field do not know the meaning of most words over two syllables or at least pretend to be that ignorant. So keep it simple for them, pithy and filled with color, but only simple words.
