Is the human fetus a parasite according to science?

Hi Gale,
You've posted this about a bajillion times to different websites over the past couple of weeks (I haven't checked them all, but your name seems to be coming up a lot).
EvC won't be visibly hosting it. Fear not, many of the numerous blogs, news commentary sections and forums that you have posted this to will keep it up for you and I'm only hiding it - it will be visible to the genuinely curious.
We'd be happy if you decide to stick around and contribute to the ongoing discussion here, but your scattergun approach to posting this piece doesn't give me much hope for that prospect.
