Actually I'm not because only the mother for some reason can make that call. If she wants to keep the child I'm on the hook for support regardless. But for me personally I'm happy with having kids.
Also abandoning them with someone who will care for them is not the same as killing them.
Which is why there is NO reason for elective abortions. Can't take care of the child, leave it with a safe haven/hospital.
You are on the hook for financial, not life-sustaining support. Neither is the mother.
Look, you aren't reading my posts. I pointed to (twice now) the posters advocating simply removing the "child" from its "life support" (mother), not shooting them in the head.
