The whole idea of not being able to touch or be close to her lovers or loved ones. That pain is an essential part of the Rogue character. Getting a cure of this ailment is something Rogue faced before and she refused it.
2. Yes, because it was dangerous. If it hadn't been and she had taken it, it would have made sense.
Uh the cure itself is dangerous because humans want to use it to oppress other people and control mutants. That in itself is WRONG. Its like trying to cure your gayness or trying to cure you from being black because the majority is white. Its not just about the not touching thing its about BEING WHO YOU ARE!
3. For some mutants, maybe. Namely the ones that do not want to take it and whose powers do not affect their ability to live an average life. But Rogue cannot even touch people! That is torturous. Taking the cure is not oppression if she wants to take it and it will free her from being a prisoner within her own body.
Again this is the point of the character. Here is what you are too closed minded and refusing to see probably because you supported this turkey in 2006.
Let's say Rogue didn't take the cure. Let's say she goes to Alcatraz, and using her powers she is able to stop or at least temporarily help stop Jean. What you are in denial about is that Rogue's powers can actually be used to save people. She can use her powers to save lives instead of wallowing in her own selfish depression of what she can't do.
A person that can't walk or has a handicap can still live a productive life. You can still be an important person and you can still live your life without having something your normally thought you could always do.
It its NOT a part of Rogue's character to allow this to happen to herself. Does she consider these things? Yes. Does she feel conflicted about them? VERY YES! But she never succumbs to these urges, this is the part of the purity of Rogue's character.
When writing X-men 2, David Hayter wanted Wolverine to have sex with Mystique disguised as Jean. Dougherty and Harris wrote that out because they thought it was ridiculous for Wolverine to have sex with a substitute. And that was a more effective move. Seeing Logan confronted with his personal sexual fantasies and desires and being allowed to fulfill them, but Logan rejected it. Logan refused a A FALSE fulfillment. It was much more powerful when Logan shoved Mystique off even after she took the form of Rogue, and he told her to get out. That was Wolverine to a T.
4. "My poor judgement"? Hello! We are taking this a little too seriously, aren't we? What is the need for a personal attack on my judgement?

And anyway, the fact is that it was
supposed to be permanent. She
thought it was permanent, or else why on earth would she have taken it? So your point about it not being permanent is moot, really.
Your argument itself is poor and overlooks the fact that in the epilogue in the movie they leave the cure open ended by saying, OH MAYBE MAGNETO CAN GET HIS POWERS BACK! Doing such a thing as well as "curing" Rogue and saying it was OK so life wouldn't suck for her is emotionally irresponsible.
5. It doesn't go against Rogue's build-up at all. She is a scared teenage girl who was jolted out of her life by a tragic event in these movies. Your error is in assuming that this version of Rogue is the comic book one. She is not. This is a different take on the X-men. Shouldn't everyone know that by now?
The character itself was truthful to the basis of Rogue. X-men 3 ruined that. She was a teenager when this happened to her in the comics. All those things above were true of the comics incarnation as well. Yes this was a different take, but its all part of why X-men 3 was such a blatant misstep that ruined the franchise, they did so much screwed up ****.
Its a different take, but X-men 2 still effectively said that Jean would NOT take Wolverine over Cyclops. That's true to those characters. Jean loves Scott and wants to be with him. That simple. X-men 3 went back on that and ruined it.
6. Oh, okay. Yes, that selfish cow, wanting to be able to touch those that she loves and live like a normal human being is supposed to.

Its easy to call her selfish when you know that you will probably never have to experience something like that.
We aren't talking about myself. We are talking about Rogue. Essentially in the movie, Bobby is being an ass and cozying up with Kitty even though Rogue is his "girlfriend." Rogue takes the cure, a cure that might not even be permanent, so she can touch her immature teenage boyfriend. That's the epitome of selfishness. Teenagers are selfish creatures that require immediate gratification. They don't want to take responsibility for their actions and they take sexuality lightly. Rogue was part of a greater cause, instead she chose to reinforce racism and oppression for her own selfish needs.
Does a person like Beast not suffer as well? Beast can touch people, but look at him? He sheds fur and he no longer looks like a normal human. Beast didn't stab himself with the cure so he could look like a normal person again. Nightcrawler has a forked tail. He was tortured and brainwashed by Stryker. And yet he is still one of the kindest and most gentle people alive. Did Nightcrawler not suffer as well? Why not give Nightcrawler the cure so he can live a normal life as well.
