Again: Tony gave Pepper armor in the comics for entirely different reasons than what you guys are asking for. Tony made the Rescue armor because Pepper went through the exact same thing *he* did --- shrapnel close to the heart, arc reactor keeping her heart pumping, yadda yadda yadda. He didn't do it to "protect his girlfriend," because she isn't even his girlfriend in the comics. Nor is she his CEO. She's just his secretary, and best friend.
Seriously, I wish to god some of you guys would actually *read* Iron Man comics, specifically the whole Rescue armor arc. If you guys actually understood that Rescue Armor implies everything that I've said --- i.e., a storyline completely derivative of Iron Man ("Iron Woman," in essence) that makes Pepper into a superhero who goes around fighting crime --- then I'm sure a lot more of you would be saying, "Holy crap, what a *terrible* idea," too. It's a DC-type concept, not a Marvel concept.
And let's drop the whole "sexist" thing. No, I do *not* genuinely believe the Rescue armor is a "sexist" concept; I was just throwing that back at the yahoos who tried to throw that loaded term out there to those of us who are against Rescue armor. You don't like labels being unfairly placed on you? Guess what: neither do I. Keep them out of this, and *maybe* we can all have a civil conversation like grown-ups instead of stooping to flamewars.
