Except civil war would not have made what it did if it was the third film. It wouldn't have even made sense as the third film.Well if MCU had used Civil War as it's third film, the way DCEU used Batman vs. Superman then it would be a tie, but they weren't looking for the short term win. This is a long game.
Again,if you want to jump through hoops to just to prove some point that doesn't make sense,that's on you.
I presented facts. That is it. The fact you want to downplay them and make excuses is the only thing that's silly.
