Your assertions do not rise to the level of common discourse on FReerepublic, and as such I will not be bothered to refute them, even if doing so is a simple matter of pointing out elementary semantic and logical errors.
Euthanasia is ending someone else’s life through active or passive means because of a medical or quality of life problem, that motivation being the major difference from other kinds of homicide. Suicide, on the other hand, is self murder, ending one’s own life. Going to buy drugs for killing yourself with later is preparation for suicide, not euthanasia, which would be if someone brought you and especially if they gave you the drug.
What logical or semantic errors?
