I agree that the "Traditional" Feast of St Joseph leaves something to be desired, as it appears to postdate the missal of 1570. That being said, the "Feast of St Joseph the Worker" is horrendous. Why? Because, now, in 2017, some 30 years after the "collapse of communism", who celebrates the Soviet "Mayday"? Pius XII was great at politics, terrible at liturgy. The liturgy should reflect eternity, which is unchanging, and not temporality, which is a continual tempest of disordered human events. Using the liturgy as a platform to oppose political events is so very horribly uncatholic. Pius V, to be sure, instituted the Feast of the Holy Rosary to commemorate Lepanto. But today, nobody cares about Lepanto, but the Holy Rosary gains relevance with each passing year. But St Joseph the worker, while certainly an object of sanctity, is an intrusion into the established feasts and cycles of Holy Mother Church., and a violence to Tradition. And the reason for its institution is even worse. Imagine what we would have today if all the popes added just one feast politicizing the liturgy, or re-arranging it for "their times". We would have a temporal church.
The supporters of Pius XII are supporting a Pope who started us down the road to liturgical anarchy, by trying to make the church "relevant" to the modern world, rather than making modern Catholics relevant to the Mother of their Salvation. If Pius XII would have paid more attention to Our Lady of Fatima and less attention to Theodore Roosevelt, the world might be a vastly better place today, and Americans might be vastly less brainwashed.
Our Lady of Fatima, pray for us, you are our only hope.
