Actually a lot of people do want to go to the Summerset Isles to fight the Thalmor. Of course the Bethesda Softworks forums doesn't represent every single person of the 23+ million people who purchased The Elder Scrolls V: Skyrim, but I have read since 2012 on a lot of websites all over the internet people saying they want to go defeat the Thalmor and be free to worship Talos or whatever god they want to worship.
I think I have counted about over 400+ or so comments from websites all over the internet.
I think out of that 23+ million people who purchased The Elder Scrolls V: Skyrim at least probably like 6+ million people or 9+ million people could want to fight the Thalmor whenever they want to.
If I remember correctly, in 2012 a person here on the Bethesda Softworks forums made a topic about being able to infiltrate the Thalmor embassy. To get documents then sail a ship to the Summerset Isles and get a guard or a inside person to help assassinate one of the Thalmor leaders and have Ulfrik Stormcloak be able to get ships. That he managed to get someone inside the Imperial military to agree to a fleet of ships, stealthily sailing while the infiltrator clears out any Thalmor spotters before they spot Ulfrik Stormcloaks ships to land and then the infiltrator to manage to assassinate the Thalmor leader.
I actually liked that idea a lot.
