You know the fella who quoted Yoda's "judge me by my size do you?" - sorry, I didn't register who it was who said it - is that not simply a variant on "your eyes can deceive you, don't trust them"? And I think the person who said that used a ightsbare quite a bit.
If you deny the prequels (which is pretty outlandish, a bit like those three monkeys with their hands over their eyes, mouth and ears) then by extension you have to deny The Clone Wars - and, I imagine, anything else that doesn't meet your specific standards of what Star Wars is and should be (again, pretty outlandish). Funny, though, how some will practically give themselves a hernia pointing out how "flawed" the more recent parts of the Star Wars story are while completely ignoring how your limb can be severed by a lightsabre and yet still bleed. "Sigh" indeed.
As for Anakin killing all those Tuskens, he never told the Jedi, only Palpatine, and I'm sure he approved.
