Before starting, and I suspect this may be fruitless, but I'll take a shot. This thread is NOT NOT NOT NOT NOT about the Civil War.
Rather, the topic is about Ulfric's actual claim to the throne as High King of Skyrim. Do you believe Ulfric has earned the crown by right of the Old Ways of Skyrim or do you think he is a pretender who committed murdered the High King and is merely an attempted usurper to the throne?
Personally, while I do not support Ulfric, I begrudgingly believe he has a legitimate claim to the throne of Skyrim.
