Now, we have a generation of Traditional Catholics who mostly were not even alive when Vatican II happened and the major battles between the SSPX and Rome took place; it's been 30 years since the consecrations. So many of them don't even get "what all the fuss is about". That's why the time is ripe for the absorption.
This is true. But the problem isn't just with the young. We have found that many in the older generations have tunnel vision. They have been so primed to be wary of a deal that no matter what arguments are made, no matter what points are made, or changes highlighted, as long as they can fall back on "Well, Bishop Fellay didn't sign the deal", all is settled in their minds. It is the ace in the hole, the last word. It takes critical thinking to realize there's more than one way to skin the cat.
