It is how they see it.
It isn't about the mass or rejection of Vatican 2. It is about keeping the Faith. In order to keep the faith passed down to us, those innovations must be rejected but they are not the basis for our end, which is holding fast to our traditions and the Catholic Church that made saints and saved souls. They can't tell me it is the same religion.
