This is practicly a civil war debate, but they are usually just about if Skyrim should stand united with the Empire to face the Thalmor or if the they should leave Empire because they're spineless bootlickers, throw in a few racist Stormcloak supporters and a headshopping Empire and you got the average civil war debate.
So I want to keep this topic about the throne of skyrim itself. What about Empire corrupting the moot and placing airheads on the throne and Ulfric in how he killed the High King. Should Torygg have been elected High King due to his suggested lack of will to actually do anything of importance? About Ulfric using the Thu'um and the tradition itself that any jarl can challange the High King to a duel.
What are your thoughts about all of this?

Please keep the racism, headshopping and Thalmor arguments to a minimum. Might be a bit hard with the Thalmor though.

When I shop for heads I prefer the name brand models...

In all probability Torygg was not elected High King, as the son of the previous King he was next in line to the throne and his succession would have been automatic. According to the Pact of Chieftains, the agreement by which such things are regulated, an election is only necessary if a High King/Queen dies without a blood heir or if the existing sovereign is deemed unfit to rule. Otherwise the Moot only meets to acknowledge the succession, not to decide it.

Fault on both sides. Ulfric was raised with the Greybeards, and was specifically told that the Thu'um shouldn't be used for anything other than the glory of the gods. He forcess Torygg in bewteen a rock and a hard place: if Torygg refuses a duel, he'll seem weak and not a rightful king. If he accepts... well, he'll get killed by Ulfric. Ulfric, rather than winning by force of arms alone (which he should have been easily able to do,) decides to use his Thu'um. Other aspects of Ulfric and how he runs the Stormcloaks makes me question if Ulfric isn't just a standard despot masking as a revolutionary.

The Empire, understandiby, is trying to fight against the Thalmor. However, rather than try and give concessions to Skyrim, they try to keep Skyrim under control by making sure that a High King who is either malleable or a supporter of the Empire gets elected. This makes them come off as pretty much a larger corrupt country that's picking on the little guy. Weather or not this is true (we haven't seen much of the Empire beyond how the Legion acts and the gripes of the Stormcloaks, so it's possible we're all missing the larger picture) it just doesn't look good once it explodes.

You can also say that Ulfric simply called on a much older tradition by using the Thu'um as nords used to use in battle all the way back to the dragon wars till Jurgen Windcaller lost his battle. Though does it really matter if he used Thu'um or not? Torygg was already doomed either way.

^This. The Thu'um was given to the Nords for the specific purpose of using it in combat against their enemies. That's what Kyne wanted, that's what she intended. That tradition predates Windcaller and his Way of the Voice by centuries if not millennia. You can't claim Ulfric "violated" tradition without making the same accusation against the Greybeards. They are using the Thu'um the way Jurgen Windcaller intended, not the goddess who gave it to their people in the first place. I'm fine with choosing the will of a Divine over that of a mortal.

Follow Parthanax (?) and the grey beards.

Kyne and Paarthurnax gave the Thu'um to the Nords as a way to combat Dragons. Not to make war amongst themselves. A nord shouting at another nord is not the "tradition" they had in mind.

They gave it to them to use as a weapon in combat. You don't give a warrior a bigass sword and then say, "but only use this against Enemy X and after that you can't play with it any more." And nowhere is it indicated that Kyne had any problems with them continuing to use it against their other enemies down the ages. That may have been Windcaller's opinion but that doesn't make it fact.

And the only reason his opinion prevailed is because he Shouted down those who opposed him. Sound familiar?

Nah I don't buy that. I really don't think Kyne would give all her kids shotguns to shoot themselves with. If it weren't for her relationship with the Nord race I'd be inclined to agree with you.
