For anyone to attack you for your interest in protecting all life, I would question why they are posting at FR to begin with.
The opposite of pro-life is pro-death. For someone to try to diminish what you do here is dishonest and preposterous.
People who are killed for their organs or in a bank holdup are not taken out by free will. They are murdered. Killers are pro-death.
As I noted earlier, ALL of the pro-life groups that I am familiar with (National Right to Life, Priests for Life, American Life League, etc.) are just as opposed to euthanasia as they are to abortion.
My guess is that there are some people who are pro-euthanasia but like to tell themselves that they are pro-life. It's not unlike what we went through with the FRiberal Rooty Rooters.
