Speaking JUST about the premise of the Civil War (NOT commenting on all the other problems being tacked on here)... it's taken me awhile to get a feel for the "issues," and after reading Civil War #3, I feel an "opinion" coming on... and it's not what I thought it would be, or what I think Marvel is obviously going for.
The intro to Civil War #3 reads: After Stamford, connecticut is distroyed during a televised fight between the New Warriors and a group of dangerous villains, public sentiment turns against super heroes... Advocates call for reform, and a Superhuman Registration Act is debated, which would require all those possessing paranormal abilities to register with the government, divulge their true identities to the authorities and submit to training and sanctioning in the manner of federal agents.
Some heroes, such as Iron Man, see this as a natural evolution of the role of superhumans in society, and a reasonable request. Others view the Act as an assult on their civil liberties...
If they want to make this all seem more "real world" then let's get real. I know I'm glad that police officers, soldiers, federal agents, etc. are TRAINED and "licensed" (for lack of a better word)... as they are given power over others and need to be held accountable.
In REALITY can you imagine any of those groups protesting that it is a violation of their CIVIL LIBERTIES to require them to attend a police academy, basic training, or any other process that has been developed, before they can carry a weapon, enforce the law, etc...? I'm mean, how nutty would that be?
We submit to training, a test, an identification process, and rules to hold a simple drivers license and no one associates that with civil liberties violations. (Ok, some do, but they are kinda "out there"...)
Why would superpowered individuals, who have GREAT power not expect to have greater responsibility... hmmm? In that I don't think that Peter is acting out of character by registering. (Captain America on the other hand...)
The unmasking -- which was not part of the original idea for this story -- is a different story. The Act doesn't require a PUBLIC reveal of their civilian identities, so I don't buy that Peter would do this. The government employs thousands of agents with SECRET identities... this is not a new concept!
You could argue that the Act was rushed and not properly written... they aren't really giving us details... but I don't think the premise is outrageous, and it certainly doesn't sound like something that would qualify as a civil rights violation... worth fighting to the death. (But I guess fight in court isn't quite as dramatic...

)
And, I certainly wouldn't hold up Patriot & Speedball as examples of nobility. They are not acting like heroes to me, at all. I don't know much about Speedball, but his denying ANY responsibiliy for what happened -- when, where and what they did WAS reckless -- comes across as peevish and immature. A little training might benefit him immensely. If I were She Hulk, listening to him whine that signing that paper was equal to admitting guilt (when it was more a chance to register and not be punished for his carelessness), I might have slapped him up side the head too.
As for the way they are approching the ones who are not complying... Is that what Captain A has the most problem with? Not sure I get why there isn't education about the requirements of the Act (as in, what does this new accountability look like), and time given to digest it... Oh, yes I do... we have to have a reason for the heroes to be fighting each other, which is the real reason for the story.
