The interpretations set out by Vatican II concerning various existing teachings.
I have met Catholics that reject these interpretations. Catholics who insist that non-Catholics cannot be saved
You possibly misunderstood – either the Council statement, or the Catholics you accuse. This is actually a technicality (not that I’m into such things – I’m not!). But salvation is still considered to be “through” the Church, so that there remains at least an indirect relationship of the non-Catholic to the Church. This was recently discussed slightly more by a guest on CAL. Again, I’m not fixed on such things, but there is apparently a misunderstanding regarding the dogma: what it was, and what it is.

…that Catholics should not attend any services whatsoever in Protestant Churches etc.
There’s still a general prohibition against joining such services (not “attending”). IOW, there can be no active “paticipation” except under certain formal approvals such as official ecumenical prayer events, etc. I think most Catholics understand that attendance for legitimate reasons (funerals, guests at weddings, etc.) is allowed.
I’ve even met a Catholic that used the term “heresy” to describe parts of Vatican II documents.
I did hear that with my own ears once, from a caller to CAL. Note that the host & guest criticized the caller’s statement (rejected it outright). The host then described the caller as “a radical traditionalist who rejects V2 completely, and there are a minority who do so, but those Catholics are not in communion with Rome.” (paraphrase, but close)
there are also Catholics who speak about OF Mass in terms approaching contempt.
See above comment. (It’s the same group.) I have never heard a non-“radical traditionalist” speak contemptuously of V2. However, I have heard, heard about, and read (not limited to this forum) hundreds of faithful Catholics speak contemptuously of the many abuses, errors, misinterpretations which followed V2, and which frankly probably most Catholics now associate with V2.
Are you trying to tell me that there are not Catholics who hold such views?
The number of Catholics who claim that the actual literal official statements of V2 are “heresy” is such a negligible number that it is not worth wasting our keystrokes on. For example, the caller I mentioned above is, IIRC, part of some tiny, private group that holds their own Eucharists in a manner which they believe is more authentic than what’s typical in parishes. I have no idea if the presider of such Eucharists is a validly ordained priest in communion with Rome, or if he is from a splinter group. Just don’t have information about that, but I do know that her group will not attend Mass in any diocesan parish.
Also, I’m actually not convinced that she rejects all of V2, but it does appear --IIRC – that she rejects the N.O. I also have no idea as to whether alternatives to ***an English NO ***
–alternatives which were re-affirmed by V2 – are available where she lives, because in so many places they are not. V2 did not do away with the Latin Mass. (One of the great misreads of the Council.) It additionally embraced Mass in the vernacular, and did not declare that Catholics were required to attend vernacular Masses. However, because of the wholesale (unauthorized) discarding of the Latin, many Catholics have found themselves with no alternatives to English Masses, which would in itself probably not be a problem (a respectful N.O.) for many of those Catholics had there not been such unauthorized relaxations of the form of the Mass, along with the change in language. Such lack of options certainly doesn’t excuse refusing to attend Mass (if that’s what she’s doing) with a validly ordained priest in communion with Rome, but again, I have no information that she and her small group are doing that.
Anyone who speaks contemptuously of the abuses and actual heresies which followed the Council is entitled to do so. Just as citizens of the U.S. are entitled to speak contemptuously about the great ignorance of the U.S. Constitution by many Americans – such as people who misapply the terms “equality” and “rights” where they do not belong.
