That's a terrible response; a very bad abortion argument that isn't likely to convince anyone anyway. The most you might get is "lol lower tax politician is a hypocrite", though Ron Paul's position here is simple enough: he sincerely believes that private charity or state level government programs are enough, so it is a non-issue. Whether he's right or wrong about the facts is another argument, separate from both abortion and hypocracy.
No hypocrisy is even required when someone does not live in a little place called "reality" and has outmoded 19th century attitudes toward women.
1) If women were not sluts, there would be no single parent homes or women who get pregnant by accident. Therefore, private charity should be sufficient when someone who is not a slut and has children falls down on their luck.
2) Sluts deserve what they get. They must "take responsibility" for their wantoness by having the child, giving up all their hopes and dreams, and raise the child in poverty.
3) What about the kids? Why should I have to pay for them? I am not a slutty slutty woman!
But, coming back to the argument there... you're basically saying abortion should be allowed because the babies might be poor, and that would bring budgetary pressures.
And crime, and suffering.
Do you actually expect people to agree that the solution to poverty is to murder the poor and potentially poor? Hell, let's cut the loaded word 'murder' out: do you even expect people to agree that it is better to not live at all than to live in poverty?
That is kind of the point of being pro-choice. Mom gets to make the decision for herself what is in the best interests of herself and the non-person growing inside her.
Also, if I take your argument to its logical conclusion, namely that life is better than non-life and that this brings about moral obligations, we are all obligated to take every chance we get, however odious, to reproduce.
We owe NOTHING to a fetus, because they are not beings posessing any of the characteristics of a morally relevant entity (no conscious perception, no pain, no thoughts or experiences etc. It really does not matter what ethical system you use. Deontology, Consequentialism, Pragmatism, Virtue Ethics...). However, we do have obligations to them after they are born (or at least viable) because they do have these qualities. Thus, any talk about the state of existence of a child is contingent on them being born.
