Yes, at all. You don't seem to understand - I'm not saying Ted isn't a bad person because the girl might be picked up by someone else. I'm saying that the analogy is bad because (among other reasons, which you continue to ignore) the girl might be picked up by someone else. That is not the case with a pregnancy.
No, it doesn't. Of course, it's a sliding scale. Analogies can be anywhere from very good to very bad. Obviously, the less good the correspondence, the less good the analogy. Yours, for the reasons (note: reasons, not just this reason) I've given, is a bad one.
I do not understand the reference to the 'force' here.
Yup, it is. That possibility is present for both situations, so it doesn't make your analogy bad.
Comparing aliens swooping down to someone coming by (which, after all, just happened) is ridiculous.
And, of course, you've still not even addressed the other two points I raised.
