Should the President veto the legislation? - Yes.
Should Congress over-ride the veto and expand the research as suggested in the House bill? - No.
If you faced the choice that the President has made, what would you have done? - Same thing, if not more fervently fought against it.
A) People are willing to adopt these embryos, but there is little infrastructure to enable it. Those who say they are useless and good for nothing else but discarding overlook that fact.
B)This has been a lynch-pin issue for pro-abortion advocates, since governmental acceptance of this practice would be an official statement that life does not begin at conception. If we can experiment on embryos, then either they aren't people, or we allow using children for scientific purposes.
C)You have to draw a line somewhere. To me and millions of others, once an egg is fertilized, the process is begun. Some say that since they have never been in a womb that they don't count, but I again assert that they are viable lives that when implanted become children. Sperm isn't. An egg isn't. You have to draw a line somewhere, and that is the most ethical place to draw it, imho.
