Oh, come now, I think the debate should continue - so long as it remains calm, rational, and devoid of hostility. The EoD version of this discussion didn't do as smoothly.
Perhaps we should make some other thread where "The Force vs. Magic" can continue, then?
In any case, let me address Kas'Im's representation of Legilimency and Occulumency:
Anyways I just read up on Occulumency, and it seems most force users would be able to counter it.
I quite disagree, Kas'Im. I'll try to address each of your points.
It doesn't require any magical power or anything, just a strong will and someone who can control their emotions well. All it is staying calm, and emptying your mind. That's it.
(taken from the Order of the Phoenix, page: 519)
Snape: "Occulumency, Potter. The magical defense of the mind against penetration. An obscure branch of magic , but a highly useful one."
Here, we have Snape, an extremely proficient Legilimens and Occulumens, saying that Legilimency and Occulumency are both magical abilities. Hence why Muggles (non-magic peoples) and - therein - Force users themselves would be unable to counter Legilimency.
Someone like Sidious would most likely be able to counter even Voldemort's Legilimency, considering how well he can control his emotions, and how strong his will is.
Sidious, despite his natural affinity for deception and secrecy and his immense will, wouldn't be able to counter Legilimency - especially from Voldemort. He was able to fool the Jedi Council because he was a master of a Force based technique that shielded his presence from them - as well as simply being cleverer and smarter than they were.
And Snape stated when teaching Harry that eye contact was often essential, so any force user without eyes, such as Visas Marr would most likely have an added advantage in defending against it.
Snape: "Time and space matter in magic, Potter. Eye contact is often essential to Legilimency."
The keyword, of course, being "often". Voldemort, who, again, is the most proficient Legilimens that the world has ever seen, may not be bound by the same limits and dictates that affect other wizards.
For example, Illustrious - in our debate - brought up how disapparation and apparation "is difficult" and "requires intense concentration", and yet - in this very book - we have Dumbledore and Voldemort dueling, and both of them disapparate and apparate extremely easily.
You have to factor in that Voldemort and Dumbledore are the two most powerful wizards in the world, and are not bound by the limitations of the average wizard. They are quite a bit better than every other character in the series.
Voldemort simply has too great of an arsenal for any Force user to compete with.
You brought up Sidious, of course, correct?
Voldemort and Sidious share many similarities: great power, great potential, great intellect, ambition - as well as both being the most evil and ruthless of their respective universes. They also share a similarity that would spell doom for Palpatine if he ever dueled Voldemort.
He's devoid of love and positive human emotion.
Voldemort is capable of possessing people who do not hold intense amounts of love. He was able to possess Harry, who retains intense emotions of love - only for a few seconds - due to his intolerability of love.
Voldemort could simply possess any evil Force user and force he or she to do his bidding. Or walk them off a cliff. Or impale themselves on their own weapons.
Hence why I say, Voldemort could comfortably defeat any Force user in Star Wars.
