There is something disturbing to me about women who choose this for themselves. I see them in my hometown. I will refrain from mentioning the specifics, however these women are all (every one of them) from a certain small European country. They come here for the farmland and to raise ridiculously large families. I have a serious aversion to these types of families. The women are all ages, and they always seem to be pregnant when you see 'em. Pop out a kid and get pregnant right away. Eight kids is a small family.
Part of my aversion is the way it alters my view of the women. They look more and more like pure flesh. Every year they look more and more used up. Food for the kids. Raising kids. There seems to be nothing else to their existence. It goes against everything I care about.
The other thing is the amount of land these families use and the spread of nepotism. A simple case of one worldview going against my own - on what I consider to be my home.
I don't care if the family is rich or poor. It doesn't matter to me. Families this size represent a different approach to the world. In my opinion, it is an approach which should not be encouraged.
I have nothing against a single individual, but I do disagree with this style of building the world.
