well its true that imperials have not been kind to the nords but nords are very well known to be raciest. i think the imperials are just mad that the nords are fighting them this much in there time of need when the ban of talos was not something they choose. it was a do this or alot more people die type thing. other than the talos ban i cant see how the imperials are forcing a different way of life on them and again talos ban was the thalmors idea not imperials. i also think imperials are playing the part of keeping cool with the thalmor and just waiting until the time comes.
this was on another site where i posted this. someone asked a similar question/statement about why dont they just leave and this was my response.
I agree with that they should just leave skyrim. But i think the reason there is a rebellion is because the imperials have been focusing on the thalmor and not really watching there people. before the events of the great war (it would seem) the nords were happy. All providences were happy and together with the empire. But then before and during the war the empire lost valenwood, summerset isles, black marsh, elsweyr, and hammerfell. also to note is that black marsh invades morrowind and they are also basically lost and high rock (not part of the empire but are allies) gets invaded by the thalmor. i guess the imperials want skyrim for a couple reasons.
1. Pride-there all thats left of the empire. they dont want to lose them too.
2. Man power-nords are good fighters i mean look at the stormcloaks. they need there help to fight the thalmor not for them to be there enemys
3. Strategy-Cyrodiil is surronded by what is now enemys or neutral providences. Skyrim was used during the great war for the imperials to fall back, regroup, and take back cyrodiil. Skyrim has no one north of it and well is a good strategy point. if the war didnt just happen and all the other providences hadnt been lost or left the empire then i dont think the imperials would go to the trouble of fighting in skyrim. in history they generally just let groups who want to leave leave. so theres my point on that.
