After the Great War, a redguard should feel betrayed by the Empire and should hate both Empire and the Thalmor. So become a stormcloak for a redguard seems logic, even if redguards don't care about Talos, they just hate and want revenge against Thalmor so same interest than Nords here.

But, i have to admit i don't really like how Nords are nationalist, i don't know if they would accept ethnic differences with people like redguards, just look those dark elves victims of racism on Windhelm.

I don't know... and you, your thoughts about that?

Oh this racist talk again well i'm not surprised

Well if the companions are anything to go by, the first none Nord to be Harbinger was a Redguard so the two races have something of a record of seeing eye to eye. I, who play as a Redguard, tend to play Empire in the war though I am rethinking it. I do see it as the Empire sold them out, more the Empire didn't have their back in the Great War. And I see joining the Stormcloaks because you want to get back at the empire as a bad reason to take part in the civil war. I think it is important for Hammerfell to build allies because just based on where the Thalmor home is there is a good chance they will get hit first if the war starts again. Rather its the Nords of Skyrim or what is left of the Empire, which would be High Rock, Skyrim and Cyrodiil. We'd get Nords on our side either way from my point of view.

Just imagine if Nords (Stormcloacks) and Redguards will make an alliance against the Thalmor, it would be awesome.

Well if I was Redguard from Hammerfell then yes I would join Stormcloaks without a 2nd thought but If I was not then i would think about it a lot more on which side to join.

I see no point in racism But yeah if the Redguards and Nords made an alliance together would be really cool!
