I did a lot of reading about Thalmor yesterday, mostly because I wanted more lore information on the Mer. I was having trouble deciding between Bosmer and Dunmer, and if I wanted to join Stormcloaks or Empire...well, I have since decided ;P I mean, if I chose one or the other I know I don't need to roleplay that I'm part of Thalmor (even though I could) and there is probably quite a few Elves that don't even like whats happening...but it did help my decision

Plus, Stormcloaks seem a bit racist toward Dunmer and other species/races that aren't Nord.
