Step1
Learn how stem cells are harvested because this is where the controversy begins. The majority of stem cells are harvested either from 4- to 5-day old fertilized eggs that are to be discarded from fertility clinics or from aborted fetuses. The debate is fueled by how the stem cells are harvested because pro-lifers believe life begins at conception.
Step2
Recognize valid points on both sides of the argument. Those arguing for stem cell research believe that stem cells may provide cures for incurable diseases. Those against stem cell research argue that harvesting stem cells from aborted fetuses is wrong because they do not believe in abortion.
Step3
Explain why you believe or do not believe in stem cell research. Simply stating that stem cell research is wrong without providing any reasoning for your beliefs does not open any doors for debate. If you believe that stem cell research is wrong because life begins at conception, then explain that to the person with whom you are debating.
Step4
Speak respectfully. Highly controversial subjects such as stem cells and abortion go hand-in-hand with strong personal beliefs. Although you may not agree with the other person's beliefs, you must respect the way they feel in order to have a healthy debate.
