Not to start up a debate about it, or say you're wrong or anything, but you do know that most of all stem cells used in embryonic stem cell testing are the by products of in vitro fertility treatments and procedures that are all ready done in the first place?
What this means: Almost all stem cell research comes from left over embryotic tissue from other procedures and experiments that are ALL READY being done, and have nothing barring and/or otherwise stopping them that gets either stored away long past its expectancy to even be viable to grow, or destroyed and disposed of anyways.
In other words: Stem cell research uses what is generally thrown away as garbage from other things, and has nothing to do with abortions. In fact, the most common procedure that produces it is making the proverbial "Test-tube baby". The left overs are what goes to stem cell research.
I both agree and disagree with your statement. I know that some of these embryos are not viable for implantation, but some are. when they "create" these embryos they make too many so they can weed out the non-viable ones and they almost always have some left over. This is where some of the abortion debate comes in. wether a fertilized egg is considered a baby or not. most pro lifers say yes but the pro abortionists say no.
I personally say these fertilized eggs are babies and most are viable for implant. there are actually embryo adoption programs out there for left over embryos.
This issue can be debated very heatedly by both sides of the issue, however the life or non life of the embryo is not the only problem. The fact that we are or will be spending our tax dollars on something that has been proven not to work. There is a reason there is such a push to get federal funding, its because there are very few privet groups that are willing to spend their money on something that will not profit them.
