Unsurprisingly, my own personal view is that everyone should vote according to their own personal views rather than, say, mine. I’m sure we all know not to take anyone’s views in this discussion as any kind of marching orders, but I thought I’d say it for the charity- or clarity-impaired.
Note that this thread will probably abound with spoilers. I’m not going to try to slice things up into different subthreads with layered spoiler policies. If you’re spoiler-averse, you might want to wait till you’ve read everything before jumping in.
