Don't worry. Whatever country you are in now may follow in the same route. The reason a lot of "liberal" countries aren't this way is because they have a lot more people in urban areas and relatively few in rural areas, and so the urbanites have a much more solid lock on politics, and urbanites tend to lean more liberal. You just need about 55% to have solid control over the message, and that means it's not too hard to start swinging the other direction. Lurking just under the surface are all the vices you see in Americans.
From what I've seen many of the stereotypes in the US about how liberal and socialist other countries are doesn't really hold up when you look closely. The people are just as varied in Europe and South America as in the US. You have gun nuts in scandinavia, ultra conservatives in France, religious bigots in Germany, etc. Europe is still lily-white in terms of race and despite having relatively few ethnic minorities and immigrants there is constant grumbling. You go into the workplace and there is a big gender divide. Homophobic jokes come out after a few drinks. And all the European countries are still very religious overall (some may deny it, but I can find those who think mistakenly think there aren't many religious people in California either). Go to South American and it's even more widely divided in viewpoints. Go to Asia and bigotry is easily found everywhere you look.
And let's be honest here, this pushing of intelligent design and the anti-science stance is far more due to politics than religion. It's a way to draw a line in the sand to decide who is with us and who is against us. And it is being driven by extreme positions within a party. With a two party system we're stuck with each party having to put up with the nut cases on the fringe who can drive a message. With a multiparty system that has to negotiate to form a governing coalition the fringe people will still exist but they tend to be left out of the process a lot more often.
