When I was in the seminary, there was certainly a blurring of the priesthood of Holy Orders and the baptismal priesthood of the laity. In fact there were those who wished to do away with the terms clergy and laity (as there are now, but they are the same ones back then).
Thus, it was out of the question for a priest to celebrate a private Mass!
Thus, it was out of the question for a lay person not to receive the Precious Blood from the chalice too.
Thus, it was out of the question for only the priest to receive Holy Communion.
Thus, it was out of the question for the laity to kneel for Holy Communion because the priest didn't and the laity are like priests and should stand too
Thus, it was out of the question for add ons to the Mass, like the Leonine Prayers and other prayers.
Thus, it is outdated to have Exposition and adoration of the Blessed Sacrament, not to mention Benediction, because the Eucharist is Food and Drink to be eaten and drunk, not looked at or adored and certainly it should not flow directed after Mass.
Thus, the Mass is communitarian and we should sit together and around the altar, hold hands at the Our Father, hug and kiss others at the Sign of Peace and generally intrude into the personal space of others invited or uninvited.
I could go on.
Isn't it interesting that the Coronavirus, not the pope or bishops, has brought a halt to all this post-Vatican II silliness, except for kneeling for Holy Communion. But once they realize that kneeling for Holy Communion reduces the chance of the minister or communicant touching the hands or lips of the minster/communicant, they will do so, not because it is more reverent.
