Sorry, but I don’t believe in this binary decision scenario you set up here...
Supporting evil is supporting evil. You may feel this is justifiable or comfortable. I do not.
The “right” to vote is not a mandate to support evil. You have many “rights” which you do not necessarily exercise.
That’s right, it’s not binary. Yet the fact is that if you don’t vote, you vote with the majority. So someone who didn’t vote for McCain or Romney, as flawed as they were, elected Obama by default.
