And a practical solution takes the reality into account. A total ban of abortions doesn't lead to no abortions, it just leads to unsafe abortions. In fact, countries where abortion is legal and accessible, have fewer abortions than those with heavy restrictions. So, if you want to reduce the number of abortions, you should want to have abortions to be legal. That is, if you can think practically not in a naïve, absolutist legal way.
It's occurred to me that one explanation for the apparently sincere offense that anti-choicers express when I point out the implications of the policies they're asking for and how these implications reflect on them is that they just haven't considered the implications of their position.
It could very well be that their thinking on the issue doesn't get much deeper than "abortion goes against my deeply-held beliefs, therefore abortion should be illegal."
... which has its own scary implications, since it implies that going against their deeply-held beliefs is grounds to make things illegal, and anyone holds deeply-held beliefs about way more than just abortion.
