The decline of evangelical Christians.

[Yonadav]

Don't study history through the lens of a hobbyhorse issue. The violence between Catholics and Protestants in Ireland was more of an ethnic conflict than a religious one. The Catholics were from indigenous families that had been oppressed by British invaders who were Protestant. So it was a natives verses invaders conflict. The participants in such conflicts will always use inflammatory rhetoric about the ways in which the other side is different. Hence, the hateful religious rhetoric in conflicts in which the belligerents are of different religions.

Telling people that they are ignorant doesn't make you look like you are dominating the discussion.  It just makes you look like you are trying to feel good about you.

Holy shit do I hate that dodge.

Yes religion caused the conflict between Catholics and Protestants, period. 

Catholic is a religion, nothing more. Protestant is a religion, nothing more. Both are sub sects of Christianity. And both sects also exist outside Ireland as well.

I am not Irish myself, but I was raised a Catholic here in America, so it is an absurd claim that it is "ethnic".

I have the same problem when Jews and Muslims fight over Palestine/Israel and forget polytheists existed in that same land prior to either.

Same with Buddhism. Richard Gere is a pasty white American, who was not born in Asia, but calls himself Buddhist. Sammy Davis Jr is black, and called himself Jewish.

Nobody can change their skin tone or facial features, but there is plenty of evidence worldwide that humans do give up prior claims their parents and or society sold them, leave those positions for other religions, or ditch them altogether.

You are one who is dodging reality.  The Irish were Catholic. The British were Protestant. The Protestants in Ireland are the descendants of British invaders. The Catholics are descended from the indigenous population. When Catholics and Protestants are trying to kill each other, there is another contentious factor in play.

You make my case for me, when you cite being a Catholic here in America. When was the last time that a Protestant tried to kill you? How much hatred have you experienced from Protestants? As an American, you aren't an Irishman fighting against British oppression.
