Senator Tom Coburn (R-OK) has posted a number of major arguments against embryonic stem cell research. If you go to the website here, you can find a short paragraph expanding on each of the following points. This is useful.
MAJOR POINTS
Embryonic Stem Cell Research Has Failed to Produce Any Cures or Treatments
Ethical Alternatives to Embryonic Stem Cells Exist
Stem Cells from Ethical Sources Are Now Treating Over 70 Diseases and Afflictions
Ethical Alternatives Should Be Pursued Rather Than Seeking to Save Life By Destroying Life
Embryonic Stem Cell Research Diverts Funding Away From More Promising Research
Embryonic Stem Cells Have Dangerous Side Effects That May Require Other Unethical Practices to Remedy
Adult Stem Cells Have Consistently Outperformed Embryonic Stem Cells for Therapeutic Purposes
Very Few “Surplus” Embryos Are Available for Research
Patients Need Cures Not False Hopes
