Indicative of paranoia present in those that spend too much time researching evil. Someone has to expose it, I know. A woman? Hardly.
I'm not one to withhold criticism, but it needs to be just and balanced.  So, for instance, we had the allegation that +Vigano is a Mason because he concluded his letters with a phrase that sounded similar to the Masonic "So mote it be."  But with some digging, it was an Italian expression for "Amen" that was found verbatim in pre-Vatican II Catholics Missals when translating into Italian.  There are allegations of Ecuмenical prayer simply because +Vigano addressed a speech by video to the Jericho rally, the topic of which was the 2020 election fraud.  At no point did +Vigano engage in Ecuмenical prayer.  We have allegations that +Vigano is allied with Dugin simply because, again, he appeared online at a conference in which Dugin also participated, an anti-jab conference in honor of a deceased Italian Catholic priest.  We have allegations that +Vigano is pro-jab because he said a kind word or two about Trump in trying to persuade him to do the right thing, despite having be probably THE most outspoken Catholic voice against the jab.  +Vigano realizes that praising Trump is the only way to persuade him and that criticism causes him to double down against you.  I agree that he was too soft on Ratzinger after he died, but he was probably trying to avoid being too harsh to prevent saying too much bad about a recently departed 
de mortuis nil nisi bonum.  I do think he's a bit naive about Trump being well intentioned, but in his letter he did say that he "dared hope" that Trump would do the right thing, a hope some of us don't share.  There are also criticisms of things +Vigano did or said before he became a Traditional Catholics, without any allowance for someone learning and being moved by the grace of God.
Legitimate criticism can get lost in the noise of this assaults that appear to be motivated less by objective reality than by some personal animosity against the man.
