Exactly and so IMHO was the trouble in Ulster religion was the excuse they latched on to and conned many non informed people from their own community.
My ancestor Joseph Malone was involved in the rebellion in Ulster in the first years of the 1800s. He reportedly killed 22 Brits. However considering the Malone propensity for exaggeration, I have always divided that claim by 3. Thus it is more likely that Joe only killed 7 and 1/3 Brits.
Every ship out of Belfast was being closely watched so they took Joseph to Liverpool, Scotland on a very small boat. There a ship's captain was bribed to take Joe to New Orleans. New Orleans was chosen as a destination because it was in the hands of the French. The French had no extradition treaty with England.
But in 1804 when Joe arrived in New Orleans, he learned that the Louisiana Territory had been bought by President Jefferson. It was now U.S. territory; no longer French. So Joe set out for the most outback area of the USA. At that time the former capital of the Northwest Territory and now capitol of Ohio was the most out back area in the USA. Chillicothe had a population of just 4 thousand people.
Joe walked from New Orleans to Chillicothe Ohio. To cover his tracks, he became a protestant. He also told locals he had worked for some years as a hatter in Liverpool. Interestingly enough, he never attempted to make or repair a hat in all his years in Chillicothe.
As near as can be determined Joe never attempted to make any contact with his family in Ulster.
Joseph had a son born in 1805 that lived until 1918. His name was Ben. Ben told both my Grandfather and my Dad that the revolt in Ulster was never about religion. It was about political power. It was a conflict about the political control of Ireland in 1800.. In more recent years it has been about the political control of Northern Ireland.
History is full of examples of conflict where Religion is the excuse, but political power is the goal.
When I was in school my fellow students of mostly English extraction, sang a very old folk song with the following lyrics.
God made the Irish
He didn't make them much
But a damned sight better
Than the G*D D*mned Deutch.
It appears that the original British settlers of Chillicothe disliked the Germans more than the Irish. My Grandfather in 1889 married a girl of English heritage from a very predominate family. It was considered a very scandalous marriage at the time.
So I am 1/4 English and 3/4 Irish.. a combination that is considered quite dangerous in some quarters.
