Effigy - New Logical Fallacy Proposal

It has occurred to me lately that a specific tactic is becoming very commonplace in political discourse, so I'm proposing a new logical fallacy to describe it:

Effigy - Substituting a groups' actual position or argument with a distorted, exaggerated, or misrepresented position of the argument with the intent of discrediting that group.

If this sounds similar to a Straw Man Fallacy that's because it is, I actually paraphrased this Straw Man definition to start this.

The difference is that it's targeted towards a group, and the intent isn't to disprove the position but rather to discredit the group!

So in an attempt to give a non-political example I'll use the X-Men. In short the X-Men fight for the co-existence of humans and mutants. Magneto, their main nemesis, might commit an Effigy Fallacy by stating something like:

"The X-Men must not be allowed to eradicate mutant kind!"

In this example Magneto would be arguing against mutant genocide, which is the Straw Man, but in implying that's the X-Men's position he's actually committing the Effigy Fallacy by making the X-Men seem like genocidal maniacs.

It could be noted that in the X-Men universe many humans actually do want to see humans eradicated, and Magneto might even have a sincere belief that attempting co-existence with humans would lead to disaster. However that still doesn't change the fact that the X-Men's position is not that of mutant genocide. In fact, the X-Men fight mutant-hating humans nearly as often as they fight Magneto!

There's a good chance this idea needs some refinement, so please share any thoughts in the comments below!
