If Xavier was not paralyzed at the end of First Class, then I can see them trying to put all of it together and retconning Dr. McTaggert as someone else.
I can't see anyone bringing this up as blowing things out of proportion or being too analytically since Xavier being paralyzed and Xavier/Magneto meeting young Jean Grey were both pivotal scenes in their respective films.
We've all been bringing this up like forever so you are not alone in wondering how the films can fit together.
I think the problem has been that each film has been made without fully taking into consideration the other films that existed at the time, and without considering the franchise as a whole.The filmmakers just did what worked best for the individual story they were trying to tell.
Hopefully it becomes clear what is being acknowledged, ignored or accounted for.
