Read your lore first - once your into the Stormcloaks, the upper element, won't treat you any differently. Any the initial racism, upon that - they are Nords fighting for Skyrim independence.
Could you mind they racism, as no other race - is apparently joining up to fight, against the...
As I stated before. How will the Thalmor get to Skyrim, in the first place? Move massive troops through Cyrodill or High Rock or Hammerfell? Chances are of that happening are zero - otherwise, they might as well, knock down Cyrodill first, since its closer and weaker now. The only other option...
How so?
The Empire lost - when they had Cyrodil, Hammerfell, Skyrim and High Rock.
When Hammerfell was left to its own vices - they won against the Thalmor.
That tells me some command issues with the Empire. And say the Empire lost the second War? And they are forced to conceed Skyrim to...
One might ask - how the heck, will the Thalmor arrive there.
High Rock on one side, Hammerfell the other, Empire the third and the cold northern sea.
The moment the Empire invades on Thalmor orders, they lose any legitimacy they have.
And the Empire was the only thing allowing Thalmor...
Do you have any proof, backing your Stormcloak racist-slogan? Or you just love the faction, who wanted to behead you for proximity?
(And if you start speaking, the common grunts are the proof. Then I'd slap you, cause they are the average mooks. I am meaning in terms, on the highest command...
Stormcloak.
Because in earnest, the Emperor is basically a glorified warlord. With no Septim blood nor ability to seal the barrier between Mundus and Oblivion.
Heck the Dragonborn has more claim - since they have dragonblood, like Talos and the Septim line did.
I smell a Trump fan or hater here.
I found that the worst chances for both sides are. You support the Legion, and your giving the Thalmor more area to operate in, since they require, the Empire to provide them diplomatic immunity, else its trouble for them.
Join the Stormcloaks, and you are...
Skyrim' victory
The Empire lost to the Thalmor, when they had Highrock, Cyrodill, Skyrim and Hammerfell under them. And yet the lost the Imperial City - had peace-talks with Thalmor to get peace on Imperial Lands. And sold out Hammerfell, and they ended up kicking the Thalmor out themselves -...
Of course it is, it was stated, the longer the civil war between the Legion and Stormcloaks happens - the more both strengths are sapped. But it clearly states, should the Stormcloaks win - then it would be bad. And that is very easily understandable, even by Thalmor standards - war saps the...
Then why, persay - do the Thalmor ambassador himself write.
Stormcloak victory is bad. Not a similar thought about the Empire. But point written 'Stormcloak victory = bad for Thalmor'.
Explain that...
You can't call it the Empire persay - since the original Septim line died off. Anybody else, who isn't Akatosh-blessed aka Dragonborn, is a false ruler.
So pretty much, in terms of political - Ulfric has a right to secceed, if he is High King, which he is uniting Skyrim for...under his...
Even if the Emperor is false? Not a Septim and can't seal the Daedra gates?
Even with the off-chance of the Empire being a puppet? And maybe betraying Skyrim, like they did with Hammerfell?
