This is one of the things I strongly dislike.
No matter which way I look at it, stem cell research (and everything about the research of DNA) has a lot more bad traits than good ones.
You say that they won't get to the cloning part but it's not such a big step to make after approving the general reasearch. Everything looks far away and sci fi until we find out that we're right in the middle of it.
Stem cell research would never get my vote, this isn't related to a particular religion btw.
