So this morning, let's wrap it for good: the majority of the comments I've seen say that political rallies like this don't belong in Azeroth at all. Players claim that they play the game to escape from the real world, and that they don't want to be confronted with real-life politics in a virtual world.
But I, and others, maintain that this is not a complete fantasy world-- it's a world populated by real people who should be allowed to express their opinions. Sure, nobody wants to have an opinion forced on them (this kind of thing shouldn't fly on a roleplaying server, obviously), but the World of Warcraft is a big one-- if you couldn't go somewhere else on Whisperwind Monday night, you could sign on to a different realm. And if you make the choice to deny one expression of opinion, you have to deny them all.
Any last thoughts? I suppose the final word on this actually came from Blizzard-- they did nothing to stop or endorse the rally, so clearly they're not against players simply expressing their opinions in game, political or otherwise. And there is good news for those of you who never want to see politics in Azeroth again-- the rally on Monday didn't exactly help Paul win in Iowa, so odds are none of the other candidates are going to be rolling a new alt.
