It seems that the common concensus is that Embryo's cannot become people? That is odd because it is take from a woman who has been pregnant for up to a month to 2.5 months... Thats a pretty large gap. The idea for the embreo is that it can be inserted into a donor, who is willing to host the child. To me that seems very wrong and selfish. Forgive me for being blunt, but there are many kids who need adoption and would love a chance to live in a family willing to go thorugh so many pains to further itself. To me that would be more sencible than "farming children" I think that phrase sums up my feeling on this quite well.
We're talking about lab-made embryos made for the purpose of stem cell research. It is not human life until it can live on its on(sometime around the end of the second trimester). Otherwise, where do you draw the line? Embryos, eggs, sperm? I guess condoms should be illegal since that kills 5983734905873094850 sperm. Or maybe the men should be forced to ejaculate into a tube so that all the sperm can be saved to fertilize the next billion or so eggs(enough to keep a woman busy for a while). The entire argument is baseless and absurd.
