Hello Matthew-
That is perhaps the most frustrating (and insoluble) problem, since it pertains to disposition.
If I demonstrate various changes or contradictions in policy and/or principle compared to those of Archbishop Lefebvre (eg., In the matter of the now greatly reduced time for making perpetual engagements), the initial reflex of many is not to suspend judgment and investigate, but to deny, or failing that, to make an ad hominem response.
I saw one comment on one of the Facebook pages (I don’t have an account) suggest that even if the entire contents of the book were true, that is no reason to write a book about it (!).
In other words, this person is simply irked that a book running contrary to the narrative she has accepted uncritically is contradicting her, and she wants it gone.
This again brings us back to the problem of disposition.
Some folks in the SSPX love their chapels because they live close to them.
In fact, they have probably uprooted their families and changed jobs just to be close to that SSPX church.
Moreover, these families will have to say "adios" to their friends, relatives, their children's friends and their schools.
Uprooting is very hard on families, friends, and relatives.
In addition, these families become very uncomfortable in seeking another chapel that is perhaps three or more hours
away as relocating to a new chapel would cost extra fuel, and that would eventually necessitate another job search
and relocation, which would also cost money, never mind all the substantial financial contributions that they have
made to their current SSPX chapel.
So, they would rather imitate the ostrich, which buries his head in the sand and hopes that the storm blows over.
After all, it is more comforting to believe that Satan will never be able to take over Rome and the Papacy,
and that the Church will prevail even in the darkest times.
Oh, yes, your book is putting some people outside of their comfort zone.
And that is the reason for their "conspiracy theory" strawman attack.
It's all about money.
