All right, now for my opinions:
Personally, I support the Stormcloaks, as I believe Skyrim should be free. That, and mostly, I tend to like the rebels.
Let's face it. A lot of people who oppose Ulfric call him racist, covets the throne, a barbarian, traitor, etc. Some of that may be true, like going against the Way of the Voice, which should only be used for worship(except for the Dragonborn), and the poor treatment of Dunmer and Argonians in Windhelm can be seen as racism. But none of us truly know what these virtual people are thinking or why they do these things.
Like the Ulfric vs Torygg deal. We don't really know if Ulfric shouted Torygg apart, shouted him to the floor, then killed him with his sword, or whatever. All we know is Ulfric used the Thu'um in combat and killed Torygg.
We don't know if Ulfric hates anyone who isn't a Nord, or will accept anyone who fights for him. He does have Redguards in the Stormcloaks, so maybe he hates/is distrustful of anyone who's not human? Who knows. But none of us can say that Ulfric is for sure racist, or only covets the throne.
Let's look at the facts: Ulfric killed Torygg. He used the Thu'um in his fight with Torygg. The Dunmer and Argonians have poor living conditions. The Stormcloaks mainly have Nords.
I will say the Civil War is Ulfric's fault, both in the sense he killed the High King, and didn't
seem to think about just asking Torygg to declare independence from the Empire.
Well, my brain is tired of this, and you guys have too much time on your hands.
Also, I must say, when having a debate like this, it's important to see both sides of the argument. Or not. I don't know. I suck at debates.
