There is an explanatory text with the vote, though. I did it to win favour with the Military faction. You were larger than our faction and should be able to stomach a single hit.

That's kind of what I meant when I said you had to show some proof of being our ally; You can't turncoat on Pizza and then turn right back because of a single vote when you've harrassed us up until then.
That's my take on it, at least. We can fight over it tomorrow in Civ!
