SpectrumRider:Most Marvel Comics readers would tell you that Tony Stark was the near-fascist villain of the company's Civil War crossover
Probably true, but that just shows that that most Marvel Comics readers misread the story.
Tony Stark is the grown-up superhero. Similarly, his Mighty Avengers are like the 30-something answer to the teenage angst-ridden New Avengers formerly run by Captain America.
Wolverine and Luke Cage and Spider-Man and all those other New Avengers types think that Iron Man is a near-fascist government stooge because he was instrumental in forcing superheroes to become registered law enforcement agents.
On the other hand, Tony Stark looked at a situation where superpowered vigilantes were running around breaking all sorts of laws and . He also recognized that voters and lawmakers in the Marvel Universe do not actually know which superheroes are the protagonists and which aren't, and that, sooner or later, masked guys with built-in WMDs running around and beating the hell out of people just because they're "evil" was bound to end in tragedy (and much more stringent regulation than he proposed).
Captain America was a long-time opponent of vigilantism prior to his appropriation by the Marvel editorial board as a lame anti-Patriot Act metaphor.
You can read the Civil War storyline as a story where Tony Stark is the villain if you want (many do), but you can also read it as a story where one of the superheroes grows up. Cops and prosecutors don't have secret identities at all, and they get by; Iron Man's compromise legislation at least gave superheroes the same protection we give CIA case officers.
Iron Man has been doing as little as he can, given his position, to punish the "good" superheroes since the passage of the registration act. How many times has he let the New Avengers sneak out the back door, now? To call him a near-fascist villain just because he saw the writing on the wall (and the Fourth Amendment...) is to fundamentally misunderstand the character and his place in the Marvel Universe.
