Does anyone here know anyone who actually supports Pfeiffer or has supported him in the past?
That's kind of vague.
I supported him in the past -- when he was an SSPX priest, for example. And even when he was a pioneer in the fledgling Resistance in 2012.
But then came Pablo, and his attacking all his fellow Resistance priests -- including Bp. Williamson. I had to start opposing him then (in late 2014), and I have ever since.
Note that there were no serious problems with Fr. Pfeiffer, at least nothing publicly known, until late 2014.
But since that point in time, Fr. Pfeiffer has only added countless reasons for my opposition over the years: Support for Fr. Tetherow, shaky theology ("Sleep with a rosary under your pillow rather than attending Mass with priests I don't approve of!"), bizarre priorities ("Attend Mass with that homo/pedo priest, rather than the Masses of Bp. Zendejas, who I consider my rival!"), support for the con man Ambrose Moran, constant lying about 97% of the Resistance priests and bishops, etc. And Pablo has become much more of a problem. In 2013 he was just a bit eccentric. Now we have the situation where a large Trad family (last name starts with Bl) is divorced thanks to their dealings in Boston, KY.
And don't forget his schismatic tendencies -- he seems to believe he's the Pope, with universal jurisdiction. Any continent Fr. Pfeiffer has set foot on automatically becomes his territory -- basically the whole world. And then any priests who don't respect that, and fail to go out of their way to work UNDER him are somehow disobedient, insubordinate, or schismatic. In the practical realm, he DOES believe that he holds some kind of universal jurisdiction. Someone should tell him that only the POPE has that kind of jurisdiction...
