Before we begin, let’s look at some definitions.
Iconoclasm (noun icon·o·clasm \ī-ˈkä-nə-ˌkla-zəm\): the doctrine, practice, or attitude of an iconoclast
(Don’t you just hate it when a definition contains the root or original word?)
Iconoclast (noun icon·o·clast \-ˌklast\): a person who criticizes or opposes beliefs and practices that are widely accepted
1: a person who destroys religious images or opposes their veneration
2: a person who attacks settled beliefs or institutions
As you can see from one of the above definitions, the term iconoclast was created to describe a person who would literally destroy religious images (icons). Nowadays, we defer to the simple definition of iconoclast.
Wherever you look, iconoclasm is everywhere. And on TV, it comes up in many instances. You will definitely see people stick closely to the original definition of iconoclasm as they deride religion. You will see people going out of their way to make fun of celebrities. That, too, can become annoying. Another form of iconoclasm is straight-up character assassination.
