Mr. Bush appreciates the potential benefit of embryonic stem cell research for curing various diseases and injuries. Nonetheless, he justifies his veto by his religious belief that retrieving stem cells from human embryo is destructive, resulting in the killing of a human being or, at least, a “potential” human being. Accordingly, so goes the argument, this act cannot be justified in spite of the possible therapeutic benefits. Mr. Bush’s conclusion is obviously not based on biomedical science but instead is an expression of his religious creed."
There! Voila! Bush Jr. deciding the future of millions, based on personal expression of his particular religious creed. He is happy to ignore congress, and the majority of Americans, who support wider stem cell research. It would not be so bad, if he didn't then try to impose his own narrow, right-wing, religious creed on the rest of us (through motions at the UN).
