Yes. People fail to look at the bigger picture, and they even cite Hammerfell as an example for why Skyrim can defend itself against the Aldmeri Dominion on its own. I have posted numerous times on this why this doesn't make any sense (actually read the Hammerfell situation--mostly Imperial troops who were purposely labeled wrong as "injured" or "invalid" to be left behind to help defend, AFTER the Aldmeri were devastated in a previous engagement/series of engagements by Imperial troops, AND the Altmer don't deal well with desert specifically). Ulfric can barely deal with a half-power single legion, and the Dominion fought against ten full-force legions, decimating three if I recall properly. At the beginning of the game, Ulfric has 1/3 of the map? Come on, Skyrim cannot defend reasonably against the Dominion. Sorry, this isn't realistic.
A long, drawn-out civil war is what the Aldmeri Dominion wants, with Skyrim ultimately barely winning so the Dominion can divide and conquer (Ulfric will not help the Empire if the Dominion goes after it, and the Empire will likely be violating their treaty to help Skyrim if Skyrim gets invaded).
If a decisive victory has to happen, the Dominion would naturally prefer Stormcloak victory. It plays to their favor.
Valenwood and Elsewyr are under Dominion control/subjugation. High Rock is not known for its military strength (although the Orcs from that general area are great). The Southern half of Hammerfell is devastated (even WITH all of the things going for them that I cited above, they still had half of their province decimated... so they're no help to the Empire anymore AND they weren't fighting anyhwere near the scope of Dominion military strength that the Empire itself was). Morrowind is mostly destroyed, and the Black Marsh wasn't going to be much use anyway. My point is that all we're basically looking at is Cyrodiil/Skyrim to defend all of non-mer-kind from the High Elves subjugating everyone on the continent. Dividing the two most significant entities is a lose-lose, except to the Dominion.
Yes, a decisive Skyrim victory might be better than a drawn-out, slow Imperial victory, but neither are optimal. Decisive Imperial victory provides the best chance against the Dominion.
Furthermore:
1) the poor decision-making of a single member of the Imperial Legion does not mean we should judge the Empire as a whole--it may be indicative of systemic problems with the Empire, yes, but I don't think we can condemn the Empire for it. Here, I'm referencing the attempted execution of you at the beginning.
2) the Empire's banning of Talos worship was only done because the Empire had no choice. Initially, this demand was refused (among others) and that's how "The Great War" started. The Empire needed to buy time to prepare for inevitable war again with the Dominion, and they had to accept terms they didn't like. No enforcement of this ban on Talos really happened until Ulfric Stormcloak made a huge fuss about it, which enabled the Dominion to pressure the Empire into allowing Thalmor agents to run all willy-nilly in Skyrim hunting Talos-worshippers. If the Dominion were defeated, the Empire would not ban Talos worship.
So, perhaps trying to form the best chance to save man-kind (and beast-kind, if you will) from genocide and subjugation should take first priority? One this is done, if the Empire refused to lift the ban on Talos worship, I'm all for Skyrim independence, then.
