I am not going to sit in judgment of them; that's not my job. The omnipotent One and Triune God will judge them, no one else. As for religious liberty, I don't believe in it, except for the fundamental right of every human being to embrace the One True Faith, which is Roman Catholicism. It really doesn't matter to me if Vatican II taught that or not; such is part of the Ordinary Magisterium of the Church, hence, it has always been infallible and will always be so. The fact that the Roman Catechism did not mention indulgences does not abrogate that dogma of the Faith.
Ditto for ecuмenism, although, it is good to be polite to non-Catholics in our secular society and to get along with them as much as possible. Still, there are "theological lines" which cannot be crossed (such as communio in sacris), however, one can point to rare instances in centuries past when Catholics and the schismatic Orthodox did concelebrate Masses together, so even this is a difficult call as to when such can take place and under what circuмstances, and I do not think that such is my call to make. In any case, it's our job to lead every individual into the One True Church, which is the Roman Catholic Church but I have no problem with being pragmatic in that approach.
