The essay agrees with the writer's disapproval of John Kerry's support for stem cell research. It argues that (1) science should not be used as a political tool or made into exaggerated claims, (2) human embryos deserve respect and rights as developing human life, and (3) embryonic stem cells are currently unsafe and unreliable for treatments. However, the essay also believes that limiting science is wrong and research should continue to find solutions, not end. It provides examples to support most points but makes assumptions about embryos and lacks justification for one argument.
