My parents went to Ireland recently, and they said they learned that the whole Catholic vs. Protestant divisiveness over there is not actually about faith at all, but is simply a culture war.
Not true. There is a cultural, social and historical dimension, sure. But this is also a question of faith. And the “war” is not only a culture one. There were lot of innocent deaths in both camps, killed by bombs, by the army or by the police. Just listen to U2’s “Sunday bloody sunday”.
They also were told that basically anyone who isn’t Catholic is a “Protestant”, even if they are atheist or Muslim. Doctrinal disagreements have nothing to do with it.
Not true at all. You obviously don’t know what you’re talking about.
I feel that many people who proclaim themselves as Christians just take the label as though passed through the family.
By propagating here the mistakes your parents told you about Ireland, that’s exactly what you’re doing too: taking the label as though passed through the family.
