Should Christian controlled southern Sudan break off from the muslim north, and become their own state?

Should the Irish Catholic break away from Irish Protestants, should the European & American Jews breakaway and carve a piece of the country from US or Europe, should the Methodist beak away from the Baptists , should the Mormons have their own country , should the US Latinos breakaway from "White" US because they are mostly Catholic, Should the Arab Muslims break away from Christians?.Should the Iranian Shias breakaway from Sunnis? Should the Sikhs or Muslims breakaway from "Hindu" India? .. and wait a minute how about we go into people's family houses and student dorms and apartments and board the whole place up with plywood and aluminum sidings and bricks in order to divide each religion into a separate enclave, then control every body like monkeys in cages. What does religion have to do with the borders of any country ? the stupidest argument I've ever heard.
