So what you are referring to in Ireland is the orange and the green?Much more complicated when it comes to the Islamic religion and it's being going on longer than anything probably within Christianity, although I'm sure there are comparisons to be drawn. My sole experience of such divisions is limited to what was going on in Ireland during the last century.
