That's what happens when you look at the past with the nowadays perspective with the aim or making demagogy, that it's easy to debunk. Abraham Lincoln was born in a dirt floor cabin with no plumbing...........like all the kids who were born in the country by that time. Plumbing was not used even in the towns, I think, so I find difficult that planned parenthood existed either, let alone that the Lincolns would consider abortion for being "poor", being rich for the standards of the time(the opposite is also true. A friend of mine who was considering abortion because she was unemployed and having economical tights and threatened with eviction. When she finally had her baby, she did it in a hospital with electric light and current water, like in her house, because it's the standard for today, not because she's rich). And not worse are his other two examples, extrapolating, again, the historical context. Moses was not abandoned in a river for economic reasons, again. It was because the male kids were killed to control the Jewish population. Again, how do planned parenthood enter in the picture, in a time where not even ultra-scan sound was available, is even more ridiculous. Finally Mary. She was not an unwed mother, she was married with Joseph. Why?, becuase, at the time, if she got pregnant and was unmarried, she wouldn't be like single mothers today. She would have been killed with her child inside(after all, as it was presumably conceived in sin). Besides, if an angels tells you beforehand that you're going to have a baby in such circumstances and you say "ok", planned parenthood wouldn't be even an option.
And all that, just for doing what specialists warn you not to do, that is, to measure the past with present yardsticks. Because, if we go to the logic of planned parenthood is not that people are forced to abort, but to offer a safe one for those who decide. If people DON'T WANT TO, again, its existence would mean the same as today, NOTHING.
