The left has always pushed the death theme, it is what they do.
There’s a difference between advocating death and accepting death as inevitable. It is something we all will share in, whatever else it brings thereafter. Sometimes the length is not as important as the breadth. Some liberals advocate death because for them life is a disease. As conservatives we love life and we enjoy the creations that life brings. It is reasonable to love one’s life and want as much of the best of it as possible until there is no more to be had, and let it end without being enslaved to years of artificial misery. I suppose many doctors see the long drawn out suffering that is sometimes imposed on the dying and want no part of it.
