I'm with psychodiva: A country's religiosity is not a reliable indicator of what it's like to live/visit there.
There's a huge difference between religious zealots and people who are religious out of tradition. It takes very few of the former to fuck things up for everyone else, whereas the latter usually don't bother others.
From my personal experience, I have seen that. I'm from Germany, which is generally considered a secular country. But, I was born, and grew up in Bavaria, which would probably show as being pretty religious (heavily Catholic) based on the criteria above.
However, it's almost more of a cultural thing than anything else. People accept their parents' religion, just like their parents did before them, but most of them don't really think much about it. Everyone, including me, uses phrases with religious connotations, like "Gott sei Dank" (Thanks to God) or
"Grüß Gott" (Greetings from God, a very common way to say hello). Generally, Bavarians don't evangelize, their church attendance is slipping, and they don't really give a shit what you are. In fact, I don't think anyone ever asked me what church I went to in Germany, but I hear that all the time in the USA.
But, I can assure you, Bavaria is an awesome place to live or visit.
