No, it's not. Saying things over and over again do not make them true.
If it's murder, then why are there not thousands (millions?) of people in prison for carrying out their power-of-attorney duties in this way?
Why are there not thousands of attorneys out there being disbarred and/or put in prison for their role in drafting and implementing living wills?
Why are there not countless hospital and nursing home employees imprisoned for not force-feeding dying patients?
Because it is not murder.
just because its legal.... like abortion... does not mean its not murder
Abortion is legal. Abortionists and those who procure them at present commit no crime.
Abortion is still murder.
Likewise killing someone by not feeding them, when they otherwise could assimilate food and water, is active participation in their suicide, if they are cognizant, or murder, if they are not.
Denying it does not change the reality of it. The proximate cause of death will be dehydration, not dementia. Death by dehydration in a patient who can swallow and assimilate water and food is by definition either suicide or euthanasia/homicide.
Verbal engineering always precedes social engineering. But it does not change reality.
