The convergence of Christianity and right-wing politics in America has brought its own problems for both, with growing numbers of young Americans turning away from organised religion to avoid the politics. Granted, most of them aren't yet declaring themselves to be atheists (in America, it seems that one has to be pugnatiously anti-religious to feel comfortable using that label), but are filling in their religious orientation as "none".
This backlash was especially forceful among youth coming of age in the 1990s and just forming their views about religion. Some of that generation, to be sure, held deeply conservative moral and political views, and they felt very comfortable in the ranks of increasingly conservative churchgoers. But a majority of the Millennial generation was liberal on most social issues, and above all, on homosexuality. The fraction of twentysomethings who said that homosexual relations were "always" or "almost always" wrong plummeted from about 75% in 1990 to about 40% in 2008. (Ironically, in polling, Millennials are actually more uneasy about abortion than their parents.)
Meanwhile, in Finland, proponents of conservative Christianity have their own problems: after representatives of the state Lutheran church spoke against gay marriage on a TV current affairs programme, a record number of Finns had resigned from the state church. (Finland, like many European countries, has a state church, records citizens' religious affiliations, and levies an additional "church tax" on church members, to be paid to their respective churches.)
