The issue of religion is a very sensitive one, which is why a lot of people have a hard time addressing it even in the context of comedy. Atheism is more common these days, and it is more socially acceptable to express atheist opinions these days. As such, it seems that at least some of the sensitivity surrounding religion has been weakened somewhat. Songs like the one in this video may serve as additional cultural indicators that this is the case.
The song seems to avoid taking sides on the question of religion and irreligion. Listeners would be hard-pressed to say what the singers think about these issues. As such, people on both sides of the debate should be able to appreciate the song to a certain degree.
People should please SHARE this video on Facebook, since it is one of the more friendly songs that addresses the topic of religion and irreligion.
