It's not comparable, there is no such thing as a "German race" (and a "German American", especially in the context of the WW2, is a complex notion), while there is an Altmer race. Especially because we are on the Elder Kings forum, where a character can be racially Almer and culturally imperial... or even nord. (edit: also, don't forget about the mod concept of Altmer pure blood).
People should definitely stop to compare Tamriel with the real world, it's never a good idea.
It actually is a good idea, since the Aldmeri Dominion does resemble the Third Reich quite a bit.
- They think they're the master race and better than everyone else, humans of Tamriel being the jews, slavs, africans, anyone who the German leadership thought to be "bad".
- They demanded land from a neighbor, which the neighbor refused, resulting in a full-scale war that lasted for years.
- Started a war. A big one.
- Before the war, they both first seized 2 neighbors by coup or force. (Valenwood and Elsweyr for the Altmer, Czechoslovakia and Austria for Germany). Nobody responded to this.
I could probably think of more similarities but these are the ones on my mind already.
