It's really silly to put down something with so much potential to really help and change things in a positive way, just because of some poorly thought out arguments. The arguments made against stem cell research are just copies of the arguments for most things, such as abortion. People need to learn to think for, and educate, themselves.
Has anyone heard Lewis Black's view on this? It's HILARIOUS! I suggest looking it up on Youtube. Though he is just a comedian making a joke, he makes a pretty valid point when you think about it.
I don't know what to say... I'm not exactly the conservative type, to say "stem-cell" research is "evil" but... still, I don't really think that using stem-cell technology in every possible domain will lead to a positive effect on mankind. Indeed it's important to find new cures, new ways to help man, and still, with every saved man, that must have died, another living one will have to suffer in the near/far future. Saving too many lives leads to an overcrowded planet... and well... I already feel quite crowded...
From another point of view, using stem-cells as a possible replacement of organ-transfers may sound like a good idea.
In conclusion... I vote for reserch FTW
