Wesley Smith uses this phrase in a post on his blog in which he discusses a proposal by Dutch euthanasia groups to create mobile euthanasia clinics. http://www.firstthings.com/blogs/secondhandsmoke/2011/11/17/euthanasia-is-heroin/
As Smith describes the idea:”My point was–and is–that once a culture starts mainlining mercy killing, it will always wants more.” The pattern is seen repeatedly. What starts with a seemingly modest effort soon expands to more and more cases. The same dynamic can be seen in the state of Washington where efforts are already being made to expand the state’s law on assisted suicide beyond the terminally ill. http://www.firstthings.com/blogs/secondhandsmoke/2011/11/16/movement-begins-to-expand-wa-assisted-suicide-law/
