His hate of the Thalmor.
His favor for personal freedoms, such as the worship of Talos.
That Imperial ***** that send him to the block even though he wasn't on the list.
Grew up in Hammerfell, which has emnities with the Empire.
The Stormcloaks helped him escape Helgen.
But upon, reaching Windhelm and learning of Ulfric's racist tendencies, he is unsure of whether he should continue to back the Stormcloaks because:
He favors racial diversity.
He is concerned and troubled by Ulfric callousness towards non-Nords (according to some citizens of Windhelm)
He doesn't really know much about the Empire other than the fact they rolled on their back for the Thalmor.
J'derras needs to know more before he can choose a side. Would/does Ulfric change after the war in terms of racial outlook? Which outcome would probably mean more trouble for the Thalmor? Any other information that might sway his choice?
Since I'm roleplaying this character exactly to what he thinks and does, I also need this info. Any help will be appreciated.

allow the Empire to concentrate on establishing a defense against the Thalmor. Supporting the Stormcloaks, on the other hand, would perhaps mean the Empire would eventually wind up rebuilt, and thus a better machine - and would leave the Stormcloaks vulnerable to an attack by the Thalmor, leading to a greater Empire being reconstructed without the threat of the nationalists, but with the shadow of the Thalmor over their heads - because there's no doubt that whilst the Empire can just about hold off the Thalmor using diplomacy and their friends in Hammerfell, the Stormcloaks would get steamrollered.
