The Society of St. Pius X trusts Archbishop Lefebvre.
This is completely false.
The Resistance trusts Archbishop Lefebvre and continues his work.
The Neo-SSPX, which is what XavierSem refers to, is ashamed of Archbishop Lefebvre. It is Menzingen who banned and criticized the book of Fr Pivert "Archbishop Lefebvre, Our Relations With Rome". It was Bishop Fellay who obtained a court injunction to stop the publication and promotion of the large collection of Archbishop Lefebvre's sermons.
XavierSem is a Trad-ecuмenist and not a true Traditional Catholic as can be seen from a multitude of his posts, for example where he strongly encourages Traditional Catholics to attend Masses and frequent the Sacraments of the doubtful priests of the Conciliar ICKSP.
XavierSem sees no problem with corrupting Catholic Tradition with conservatives who place 'obedience' above Faith, Catholics who accept the New Mass and Vatican II, Catholics who will submit to the Modernist hierarchy whenever they choose to curtail their traditional 'privileges'.
XavierSem considers that Archbishop Lefebvre would rejoice to have a modernist Conciliar bishop like Huonder dressed up like a Catholic Bishop and offering the True Mass with his doubtful Orders in a house of the Society. Who is he trying to kid?
XavierSem condemns what the Archbishop concluded about the impossibility of placing the SSPX in subjection to Modernist Rome until it comes back to the Faith. He condemns what the Society bishops and superiors, faithful to their holy founder, dutifully proclaimed for decades, that such an arrangement is impossible and would mean our death.
On the other hand, XavierSem endlessly defends Bishop Fellay who divided the Society by abandoning its principles and encouraging us to accept a deal with modernist Rome "it cannot be a trap, it can only be friends wanting to do us good". He would have you, too, let down your guard and trust the wolves in sheep's clothing.
XavierSem is a Liberal. He wants you to abandon your principles to achieve a practical unity, independent of the truth, with all those who are attracted to the smells and bells of the traditional liturgy. He dreams that in this way the cause of Catholic Tradition will somehow be served.
