This is the disagreement we're not getting anywhere on. See, I see the six movies, where the Jedi clearly show they do not have the power to crush Death Stars with their mind, as evidence that they do not have the power to crush Death Stars with their minds.

So everything that we didn't see people do in the six movies counts as evidence that they couldn't do it? How do you figure?

Since you assume, based on one line of dialogue, that they must have that power, every single example where they don't is therefore not evidence.

There is no "they". Yoda is the one that made the claim. And I'm not "assuming" anything. Like I said before, words mean things.

It is established that Yoda can move objects regardless of size (which would of course, include the Death Star), based on his claim in ESB. There is no evidence that Yoda could not move the Death Star. The fact that he didn't is not evidence that he couldn't. So why didn't he when he said he could? It is questions like those which lead to the conclusion of the character being dumb; which leads to the conclusion of bad writing.

I would posit that the reason we don't see Yoda fail at moving anything is because a 900 year old Jedi Master might already know his reasonable limits, but that no doubt is a baseless rationalization.

So why claim there are no limits if he knows there are? Why are you so determined to reconcile the rest of the series to that single line from Yoda, rather than simply admit the line was bad writing, which ended up making Yoda look dumb for not single-handedly taking down the Empire with this god-like ability of which he boasts?
