-The American rebels were English colonists, and they are betraying their own motherland.
-The Americans were very sensitive about their freedoms, and took almost every act passed personal.
-The Americans hardly have it as bad as the people actually in Britain
-The Americans hardly paid as much as the British citizens did for taxes.
-The British were the Americans protector and main financial supporter. (Note: Even though they couldn't trade with other countries, the Americans did have a guaranteed trading partner & the British Royal Navy and army served with the Americans before the Revolutionary War)
-In the British media they depicted America as a rogue child needing a spanking.
-In the King's eyes this was a direct insult to him
Those are all according to the British point of view, back then. I am American, but I try not to be too biased about everything concerning our nation. In other words, I'm no patriot.
