From Infidel753:
Most of Europe has been strongly secular for decades, and in the US the non-religious percentage of the population has also been growing, with the trend speeding up in the last twenty years with the rise of “New Atheism” — though the US remains much more religious than Europe. Some have argued that even as religion dies out in the most advanced countries, it remains vigorous in the developing world, and that secularism will always be a regional peculiarity of Europe, the US, and a few other places such as Japan.
The clearest signs that this view is wrong have come from Latin America, once the demographic heartland of the Catholic Church, where the dominant position of religion has also clearly been faltering. The clearest evidence of this change can be seen in the growing acceptance of gay marriage, which is being legalized in country after country, and in the willingness of national authorities to aggressively confront the Church over the issue of priestly child molestation, especially in Chile. Strikingly, it’s the least economically developed countries in Latin America where religion remains strongest.
More recently further confirmation has come from a region most Americans think of as irrevocably in thrall to religion — the Arab world. A survey of over 25,000 people in ten Arabic-speaking countries plus the Palestinian territories, compared with a similar survey from 2013, shows that the number of people who self-identify as non-religious is surprisingly high, and rising fast.
