hmm, They are keep blocking everything, still India's population is raising higher than any other country in this world.
According to my readings, two underappreciated reasons are:
1) unavailability of doctors/medical centers to do female sterilizations. Women literally riot in mobile sterilization camps if the camp closes before all of them are looked after. Men refuse to use condoms or get sterilized, but women do want to limit the number of children.
2) HUGE infant and child mortality among the poorer classes. If the probability of your child surviving to adulthood was low, you'd have three to five children too.
Neither of these are covered in your glib remark about porn. You should educate yourself more about your country.
Looking at both http://en.wikipedia.org/wiki/List_of_sovereign_states_and_de... and http://en.wikipedia.org/wiki/List_of_sovereign_states_and_de..., India is not near the top. The top isn't characterized by being muslim, either. [EDIT: was "Neither are "muslim" states, though - with the exception of Afghanistan, the top "scorers" are all African."]
Islam, spread from North Africa beginning in the 10th century, has greatly shaped the mores of the people of Niger. Between 80 to more than 98% of the population is Muslim
So dimmuborgir was quite correct.
That said, yes, contrasting "muslim" and African is nonsense; I edited my post to fix that.
His statement is true in the same narrow sense as other nonsensical assertions like "No. Muslim countries have higher per capita incomes than the US" as a counterargument to suggestions the US might be doing rather well financially (without having as much oil per capita as Qatar and Bahrain). It's equally true to say "Christian countries have higher birth rate than India", but I'm guessing the original poster doesn't live in an environment where misleading negative stereotypes about Christians are commonplace.
Insinuating that Islam had anything to do with higher fertility rates is the sort of intellectually dishonest chauvinism and religious stereotyping that HN readers should be above. Couple that with a denial that a birthrate of >3 children per woman in an developing country of over a billion people might present a major challenge and you have a comment thoroughly deserving of downvotes.
