Perhaps you're right, but there are certainly causalities, just like in any war.
Not only with the Catholic/Protestant war in places like Northern Ireland, but with people everywhere who get disgusted with it and them and then reject the God and belief system that makes them both fight so much.
All too often, those who claim to be His and claim to follow His teachings are among the worst examples. You definitely can't tell they're Christians by watching or listening to them fight with or talk about each other.
"I believe." Probably one of the most beautiful, yet controversial statements a human being can make, isn't it? Don't let it get you down! Faith is a lifelong journey: seek with all your heart, and you'll find the path God wishes you to follow!
