We appreciate your questions, Seanog.  As for "separate VI & VII churches" as you put it, there would be no problem with which one retains "the "four marks" of the true church" because those marks "belong" to the Catholic Church which includes Rome and 23 other (mostly Eastern) Rites/Churches in union with Rome, no? 

As for the gender equality question, the Blessed Mother's very important role in Catholicism does not address gender equality in Catholicism for many Vatican II Catholics.  And, as for the Bon Secours scandal, it raises as many questions as other horrific scandals in the Church, past and present.
