Sort of, I just like the mask. Besides, you aren't a pony either (I hope).

Indeed, you are correct. Just thought it was funny that the mask is associated with an underdog

More on topic: Personally I find it difficult to chose one side in this conflict. Depending on the perspective one chose to see the situation from both sides are either the bad guys or the slightly less ad guys.
Stormcloaks:
Restored Talosworship
A nation openly hostile to the Dominion who have always been more longtime strategists
Said nation is hard to invade because of the environment
However:
Less troops since less nations can controbute to the army
Minimal magical understanding since the Stormcloaks doesn't seem to trust magic
They lack an intelligence network like the Empire have
No special operations units like the Penitus Oculatus
But:
The Empire allows the Thalmor to move in their territory
Corruption and infighting seem to be a part of the Elder Council
At the end of the day I am not sure who to support, but I think I am a little more friendly to the Empire than the Stormcloaks.
