I am not sure why posters are holding out Easter as a commemoration of the crucifixtion, which did not happen on Easter.
I can't speak for protestant or catholic traditions, but in my life experience the whole point of the Orthodox celebration of Easter is to celebrate the resurrection, the spiritual significance of it. The customary greeting given by Orthodox chrisitans to each other on Easter is "Christ is risen!". I actually cannot recall them making the focus of Easter on the crucifixtion and death of Chirst on Good Friday. Without the resurrection there would be no Christianity, the crucifixtion not withstanding.
I am not theological expert, but I appreciate the aesthetic quality of celebrating the resurrection, rather than the bloody torture, and death that occurred on Good Friday.
