Okay, lets get one thing straight. The Empire is not the Thalmors puppet toy. They only signed the whit gold concordant to ensure that no more innocent civilians died, and so they could strengthen their forces for round 2. do you really think that The Empire is going to stop the worship of the deity that FOUNDED the empire? Tulius and Rikke worship talos. everyone worshipped talos and the thalmor didnt notice until Ulfric started whining about it.
It isn't black or white like that (and kudos to Beth for that). The Empire signed a treaty that was pretty much put them under the Thalmor heel. The Sovielves have full freedom of movement through Imperial territory, Imperial citizens can be arrested on a whim by Thalmor representatives and Hammerfell was essentially betrayed by the Empire when they cut ties. Furthermore, the White-Gold Concordat was signed not because the Empire was worried about civilians (they weren't), but because the Imperial army was in absolutely no shape to continue the fight against better equipped, better trained and more numerous than the equivalent Imperial legions. Read a copy of The Great War, it's pretty clear that the W-GC was signed because of necessity, not an "oh, civilians died, can't fight more!".
Khajiits always getting :gun: , :flamethrower: , :swear: or :meh: up....
Well, we keep coming back, a testament to our awesomeness. Oh, and the fact that we capitalize on everything in Skyrim, selling to both sides with relative impunity.

And no, neither Khajiiti, nor Argonians are made to be slaves. Not anymore than Redguards or Nords.
*sigh* Why must people bring up real world stuff?
Why can't we have a Stormcloak discussion, in pure fantasy context terms. >_<
Uh, because Skyrim was written by humans, who made a game about human-related matters, such as liberty, racism, loyalty, religion etc. I love how much more developed Skyrim feels in comparison with Oblivion and Fallout 3, which were pretty damn black-and-white in their handling of the matters: Skyrim finally brings the much needed ambiguity.
