your posts are usually really good, but this isn't one of them.
I didn't say the parents should be involved-- in fact I mentioned that parents could bully/pressure a child into a decision as well, so your first point is just reiterated what I said. Counseling would not involve parents, if that's what you're getting at.
What other surgical procedures are children able to undergo without the consent of their parents? If you're referring to adults only, your statement would be correct. However, we're talking about a procedure that is available to minors without parental consent, and as far as I know, they don't "give informed consent for all kinds of procedures without state mandated counseling."
We would do it for abortion in particular, because, as I stated above, it is one of the few, if not the only surgical procedure available to minors without parental consent. AND because abortion is an unusual procedure in that it can be a total mind fuck for people.
I already addressed your point in saying that for some the counseling could be a really beneficial thing, for others it might not be necessary but really doesn't hurt. However, to answer your question of "what if a woman comes in and is perfectly aware of what she's doing but still has to go through needless counseling?" The answer is that she will have an hour of her time wasted on needless counseling-- what's the harm? If 10,000 women who don't need counseling have to sit through an hour of counseling just to save 1 woman or child from domestic violence, parental coercion, or suicide, then I'm for it.
