1) The concept of "maturity" (as we today define the term) being commensurate with advancing age rather than relative to the individual based upon numerous different factors is a relatively recent idea; the concept of what we today call "adolescence" didn't even exist in the Western world prior to the turn of the 20th century.

2) Whether or not girls bore young at an early age depended upon a majority of factors throughout history, as the same can be seen in aboriginal cultures that remain in the world today. Life expectancy and level of resources for the culture in question are both significant factors. For instance, the tribes who live in the infamous Lakoula Swamp region of Africa have notoriously short lifespans due to the hardship of living in that region, which is why it's not unusual for girls at age 12 in those tribes to bear young. Seamus and Scotty are correct when they say that deliberately waiting to a later age to bear young is a conceit that is confined largely to post-industrial societies. It's also reflective of how women were treated in the society in question, and whether or not they were allowed to seek careers or higher education on a similar level as the men; if they were not, then most of them had no good reason to wait to a later age to bear young.

3) Too many people do have a tendency to have anachrocentric conceits when viewing history, and they need to be careful not to assume that what is an important aspect of morality or moralism today necessarily held true in past societies, where many things were different. For example, as noted above, the idea that what we today call "maturity" is always dependent upon greater age rather than something that is relevant to individual merit is most certainly an idea confined to the past 150 years, if that. It's difficult to look at past cultures, or even other modern cultures that differ enough from our own, from the perspective of the people who lived there as opposed to our contemporary perspectives, and we need to be mindful of this.

4) I am not only around poor people very often, but I am poor myself, so I know how typical poor people tend to act. Their level of education is often poor (though certainly not always), because they could not afford to attend the best schools and often were unable to attend higher education, and the number of opportunities available to them are often far less numerous or prosperous as those available to kids who were born into affluent families. This certainly affects the number of offspring they have.

5) Food is cheaper today, you say? Only if you live on an entirely different planet than I do. Speaking as a poor person who shops regularly, I can personally attest to the fact that food is NOT cheap, even if you have foodstamps, and the government frequently proposes passing limits on what foodstamps can purchase (some justified IMO, and some most certainly not justified IMO). Food is certainly far easier to produce today under modern productive methods, but it most certainly is not cheap to purchase. If you know a place where food is actually cheap, then please let me know where it is, because I would like to move there.

6) America is certainly not the source of all evil in the world, but you cannot reasonably deny that, as the most powerful nation in the world in both a military and economic sense, it has vast influence on every single nation in the world, and its government frequently bullies other nations into kowtowing to its will on any number of matters, from economic to cultural. That cannot of power cannot exist in any nation without a measurable level of corruption, and this should be logically expected. Further, this should not be taken as an attack on American ideals, which I cherish and fully adhere to. Rather, it should be taken as an attack on the American government for all too often not adhering to these principles and ideals in both its foreign and domestic policies. "My country right or wrong" has nothing to do with principles, but is an attitude of blindly following the trail of power or the government that controls the land of your nativity or citizenship without caring in the least whether it's adhering to any type of principles that are consonant with its stated ideals. Do I hate America? Not at all, its principles and ideals mean everything to me. But do I always support what the government does? No, because it all too often does not follow those principles and ideals.

7) Just because something comes from the Bible (or any religious text) doesn't automatically mean it's garbage. Oftentimes it is, but other times it's not. Each passage and scripture should be judged on its individual merits (with consideration for the time period in which it was written), just like people from any group.
