Brian-
I am not joking when I say this. Nor am I attempting to demean or denigrate. Please get help. I am not sure if I should be more concerned for your soul or your psyche, but reading these last answers of yours, you are very frightening. As the sibling of a person with a profound disability, I shutter to think of how you look at people.
That being said- help me out on an other matter. You, who have spent thousands of bytes telling people that Scripture is not to be taken literally (with regards to homosexuality, etc.,), are telling me that we are to take things quite literally with regards to "flesh?" Is that the best you can do? Jesus ain't the Messiah until he had some meat on his bones? What is flesh made of? Cells. And Jesus, like every other human, started off as just one, from which all else is derived. The potential to be flesh or sinew or bone or brain is inherrent in each cell. Indeed look at the Noble prize for medicine this year.
Do some zygotes not implant? Yes. Do some embryos die? Yes. Do some develop with flaws that lead to disabilities? Yes. But all of these share with you and me an essential charateristic- full humanity. That you are purblind in this are does not lesson the reality.
BTW- what you need to use is referred to as "People first" language. People. You know- Human beings. Fully so.
