Sorry, but men have NO choice in the matter. None, zero, nada, zilch, nyet, nein, non, absolutely NOTHING to do with whether a woman has an abortion or not.
*IF* my wife wanted to have an abortion, and I didn't want her to, there's NOTHING I could do to stop her.
Now, I'll agree it does take two to abort, the woman and her doctor - the man/Dad/spermdoner has no choice in it.
First--I know who makes the decision legally. That's obvious enough--who holds the legal responsibility. Though, I'm not so interested in legality here as who is behind the scenes urging the woman or girl to dispose of an inconvenience and applying pressure. I point, also, to recent media murderings of women who have a pregnancy inconvenient for some man.
