Facing the reality of the situation is important. We need to see things (events in the Church, Church Teaching) as they are, not as we would imagine them to be!
Sede vacantists, ignoring the dogmatic fact doctrine, see the actions of the Pope / Council / etc and state: This can't possibly be the Pope etc.
"Conservatives" likewise state the same thing, but arrive at a different conclusion - all must be ok.
Aligning our understanding with reality (ie Truth) is key to understanding all the ins / outs of the crisis of the Church.
The SSPX is merely a symptom.
In the 70's the mantra was established and while the problems started earlier, it is easy to date the malaise of the Church to this event.
It is the first bookend, it will be interesting to see what becomes the other bookend to this crisis.
