I asked you about self-awareness, it's certainly not my standard. I don't like this instant association with Singer's ideas that you've proposed. I simply see a very clear difference between an unimplanted embryo and a developing embryo. I'm not Catholic, don't accept the Church's teaching on birth control and IVF, and am tired of the poorly reasoned positions on this topic promoted herein.
As an example, quoting the Catechism of the Catholic Church about IVF to me is pointless. It is based a believer's interpretation of God's will, not even scripture. Like much of the Catechism, and the detailed beliefs of all relegions, man is the messenger, God is the message.
Your Golden Rule line of argument is much better. I'll noodle on that one.
Here's another tack.
I have a proneness for asthma (got it as an adult, though) and arthritis runs in the family, got it in my 30s and without taking herbs I can barely walk. I also have a "funny" heart which gives me trouble now and then, since my 20s.
I guess it's too bad technology wasn't so advanced a few decades ago so my parents could have culled some defective embryos and I would not have been born since my body is clearly defective. Oh, and one parent had two kinds of cancer; maybe I'll get cancer as well.
What a miserable defective life I have.
