How is steve =/= cap? I get it but i kinda dont get it.... Im sorry if this infuriates you but i think youre the best person to answer it...
In the MCU, Steve Rogers is a person; Captain America is a character.
In the MCU, Captain America was a character created to sell war-bonds. He was literally a product of war propaganda. Steve Rogers, the person playing Captain America, had no say in what the character said or did, so there is no way he can be portrayed as a reflection of Steve Roger’s opinions or desires. Steve was an actor playing a part and that part was defined by his employers
When Steve went to the European Theatre and started actually participating in the war, he was not playing a character. He kept the name of Captain America, but he was acting as himself. He still had little to no say in how his image was used by the media or the news reels of him filmed in Europe. After the ice, Steve had absolutely nothing except for a character he played in the 40s. At that point, Captain America had 70 some years of mythos piled onto him by literally everyone except Steve Rogers. And literally everyone expected Steve to be Captain America. He didn’t have a choice in the matter, he was awake for a week and was thrown back into active duty, not as Captain Rogers but Captain America. When Fury greeted him as ‘Cap’, that wasn’t a shortening of his title, that was shortening of his stage name.
In the MCU, Captain America has encompassed Steve Rogers to the point people don’t even see Steve Rogers anymore. I know that in the comics, its different, so I totally get the confusion, but no seriously. Steve =/= Cap. Steve can’t equal Cap, he has been given little to no chance to influence the character of Cap, and instead has been forcibly shoved into the role to the point where, in WS, he is fucking contorting himself trying to make his life work.
And it doesn’t because holy crap Steve is miserable
