Given the fact that Mr. Jones is associated with the word "pig", we can see why Napoleon could potentially be a fitting name.
A pig is a farm animal best known to roll around in mud. People who are referred to as pigs are often large in size (obese fat ugly pigs).
Are these characteristics fair to apply to Mr. Jones? Yes.
Mr. Jones is a basic white man who is associated with the word pig.
So, why is Napoleon a fitting name for Mr. Jones? Napoleon was a large in size (obese fat ugly pig) who took opportunities from those who needed it. An easy way to refer to Napoleon, former emperor of France, is selfish.
Here is what Napoleon is known for:
-Restricting rights gained by women
-Invading Russia
-Destroyed all press in France by simply declaring himself king
-Beginning a series of wars
-Invading Italian peninsulas
And much more.
I hope this helped answer your question: "Why do you think Napoleon is a fitting name for Mr.Jones pig"
