If you choose either one you give your imprimatur to that one. How have you refuted my analogy?
If the length of time 'til death is the issue then make it 'a bullet to the head or slow poison.' The murderer makes you choose one. If you choose either one you have just participated and thus committed the act of suicide.
Now THAT is a better analogy.
Remember, some of us have the luxury of voting our conscious, because our state will go Republican no matter what we do.
However, to those who don't have that luxury, they are faced with this very dilemma: Slow poison or the bullet. I cannot necessarily fault those who would choose the slow poison.
There are those who would choose an unoffered option: Attacking the murderer who made you make that choice. The attack, in this case, would be a write-in vote. In that event -- sadly and realistically -- they are still overpowered, and the choice to take the poison or the bullet is given to them by others.
