I would also like to point out two things, 1: the SHRA requires that supers register their identities with the government, not the public. Spider-Man took his mask off in support of the registration act, not because he had to. 2: Being paid to perform their services shouldn't really matter to super-heroes, I don't see why that is even in the debate (maybe because its the only thing that separates the SHRA from slavery).
Now... though personally I might be anti-registration, I am even moreso anti-civil war. The only part of the SHRA that I agreed with is the part about training young supers. However, I do not think that supers should be forced into a program that trains them to be super-cops, I think it should be more like Xavier's, teaching young supers how to use their powers while offering advanced instruction for those who want to fight crime. Another argument that I've heard for Pro is that it will hold them accountable for their actions. I disagree with this, previously (before SHRA) super-heroes held themselves accountable to the intangibles, "liberty and justice for all", this act forces super-heroes to hold themselves accountable to a lesser essence, the U.S. Government. The U.S. Government has shown that it's decrees are not always within keeping with "liberty and justice for all" and if super-heroes were forced to follow the will of the Gov't they will find that they are no longer fighting for what they believed in anymore, but rather merely fighting because the Gov't told them to, and they will be forced to commit acts which are not in keeping with liberty and justice for all. The last cohesive argument I heard for Pro was that super-heroes were no longer trusted by the public after Stanford. What the hell does it matter if the public likes what they do or not? This makes it seem like super-heroes are merely pining for approval like common teenagers. As Cap once said :
"Doesn't matter what the press says. Doesn't matter what the politicians or the mobs say. Doesn't matter if the whole **Country** decides something **wrong** is something **right**. The Nation was founded on one principle above all else: the requirement that we stand up for what we believe. No matter the odds or the consequences. When the mob and the press and the whole **world** tell you to move, your job is to plant yourself like a tree by the river of Truth and tell the whole **world** "No, **you** move.""
I think this also answers POHOCOM's statement that Cap would be pro-reg.
However, all this said, I would not side with Cap and fight with his secret avengers and fight a civil war. As I said, I am anti-civil war, I would never fight fellow heroes, no matter how misguided they may be. If you want to defend your freedom so bad, take it up in court, the SHRA was a law, you fight laws with lawyers and petitions, not laser beams and shields.
Also, while we're on the subject of the Civil War, I would like to state that I disagree with the ending. Anti-regs would have been perfectly fine with just going around fighting crime, it was the pro-regs that initiated the battle and the war. Thus, all of the damage that was caused by their war falls on the pro-reg heroes' heads because the anti-regs were just defending themselves, there would not have been a battle causing all that damage if the pro-regs didn't start it. Therefore, I believe that it should have been Iron Man to surrender, not Cap.
