But the problem with having to pay for an abortion is that it is often poor
black girls/young adolescents who become pregnant

I'm sorry but are these 'poor' girls so poor that they cannot afford to buy condoms?
Are they so 'lame' that they cannot get themselves 'on the pill' once they become sexually active?

Why should taxpayer's money be used to fund operations just because they act so irresponsibly?

It is, disproportionately, the poorest who have to
carry the burden of a policy that would require the woman to pay for an abortion.

Good! It might make them think twice before having sex without using some form of contraception.
