Hit back with some hard statistics:
10-20 year reduced life expectancy
20 times more likely to commit abuse of a minor
almost exclusively responsible for the resurgence of syphilis
costing billions in health care due to STD’s
five-fold higher substance abuse
several-fold increased incidence of depression and suicide
Just a few. See narth.com or Family Research Coouncil’s excellent book “Getting it straight.”

Yep, Sodomy has a greater negative affect on life expectancy than smoking, alcoholism, drug addiction, obesity combined.
