While we don’t have all the answers, the truth is not relative. What you are demanding is basically the admission that the truth is relative in so far as disagreements with Anglicanism are concerned. The Catholic Church is not the only one in which sacraments are celebrated validly. Those denominations which have not departed from the fundamental Christian dogma, have valid baptism and therefore also marriage. Those which have valid holy orders have all sacraments valid, such as the Orthodox or Eastern Orthodox churches. The Anglicans don’t have valid sacraments because while the current rites are sufficient for ordination, the Edwardian rite was not and there is a gap in Apostolic succession. Those Anglican bishops who were ordained validly by e.g. Old Catholic bishops confer ordination validly, which is why Anglican lines are traced and sometimes conditional ordination is conferred.
Why we have to argue about such basics is that if we lie about this, what will we be true on, or true to? The accommodation of dissenting ideas is not as important as the truth is.
