Sorry, but once you start to drop the idea that sex is a thing of meaning and love, with consequences, you lose any right to oppose abortion. All the anti-life brigade then have to say is "Men have the right to this pleasure and they don't need to worry about a baby - we only want equal rights".
That said, of course casual encounters should be discouraged. The abortion industry would not want them to be discouraged; they'd lose business.
And then there is athe father of the baby.
He needs to have the legal right to prevent the abortion of any child he fathers, from the moment of conception forward. Instituting that would dramatically decrease the number of abortions in America.
Feminists seek "procreative autonomy", but procreation is fundamentally non-autonomous: it is a contract between a man and a woman.
A contract which says she won't kill the baby, and he won't desert the baby.
That contract is the basis for all civilized societies.
Jesse Jackson wouldn't quite agree :)
