Your opinion on the scotland independence movement?
I'm in favour of Scottish independence in premise, considering Scotland has always tried to separate itself from English governance and the times where being under British rule had some positives have long since passed. In execution though, it doesn't seem like it'll change much when those at the head of the SNP are very much aligned with most British policies and the problems that come with that.
Since one of the reasons you've grown to like the Prequels is their worldbuilding, what about the way it clashes with the worldbuilding from the OT? Stuff like Leia remembering Padmé,
She didn't have clear memories of Padme though, with her only mentioning feelings she picked up, something that is highly plausible for someone that's Force sensitive. That, and even in the real world it's possible (albeit extremely rare) for people to retain memories from infancy.
Qui-Gon's whole existence contradicting Obi-Wan's story to Luke,
How does Qui-Gon contradict anything? The only things I can think of when saying that is Obi-Wan saying Yoda taught him and the midichlorians thing, both of which are flawed examples. Yoda teaching all Jedi as younglings (Obi-Wan included) and Obi-Wan having another master after him doesn't contradict Yoda still training him, and Qui-Gon's midichlorian explanation only explains how the Force works and not what the Force actually is. Lucas even stated that such an explanation would've been in ANH had he found a place to naturally fit it in.
the first Death Star taking decades to build,
Even with plans for it existing and the initial layer being built, a moon-sized superweapon is still going to take years. This is made very apparent with the knowledge it runs on kyber crystals which are very rare to find in such a quantity you can destroy planets, and even without that knowledge, Han mentioning how it'd take a star fleet to do what the Death Star did to Alderaan makes it apparent how much energy was required, especially when establishing dominance throughout the galaxy with a fleet and working on the Death Star isn't close to a quick task.
nobody knows what Jedi are...
They do though. Han had heard of them but didn't believe in their abilities at first, Mon Mothma held a belief in the Force, etc. The only person who was ignorant on what the Jedi were was Luke, a farm boy in a backwater planet in the Outer Rim.
Also, is Vader not instantly arresting the Rebels on Bespin really a plothole?
It is when not only is he portrayed as being highly efficient throughout the first act of ESB, but the chances of him doing so seem very slim when he'd have to conveniently get an idea of where the Falcon was headed despite it having evaded his pursuit. Vader really had no reason to not arrest them on sight.
