The point is that a woman who finds herself unintentionally pregnant is forced into a choice. And one of the options in that forced choice is an abbortion (the other being to carry this unwanted pregnancy for nine months, endure labour, and deal with the fallout from that).

I think 100% of women would rather not be in the position where these were their options. And that's before we even talk about the cases where the woman has been raped or her life/health is at risk. So I don't think the word "want" applies in that case.
