I encourage all citizens who typically do not vote, to vote your conscience, and then lie. Already no one expects you to vote anyway, so just lie per their expectations and say you didn't vote. That way you don't have to justify or argue your choice any differently than you have in the past.

Yes it's a bit chicken s* but so f'n what? You don't actually owe anyone an explanation anyway, but you're entitled to vote. So just get on with it, and lie. Everyone is lying about something or other anyway and this kind of lie is pretty benign. And it's in the public good that you vote even if you don't like arguing about why you voted the way you did.
