Many of the arguments you gave pertain to the generic "should one have children" more so than they do to the readership of your article, thus losing a good amount of relevancy.

This is true, when I wrote this I wrote mostly reacting to the many reasons that I have heard people give for not having children. With the "but its so much work!" and "but I could be spending that money on famine relief!" arguments being the most painful to my ears. So by writing about the negative case, I didn't have space (nor frankly the expertise) to write about the positive case for having children, which you have done a great job of presenting.
