SSPX, excommunicated schismatics as its adherents and leaders are, have no place in the Roman Catholic Church given their schismatic pretenses. In place of legitimacy, like the old soviets, they are masters of agitprop and disinformation. Fortunately, as with the old soviets, you can easily determine when they are lying. Their lips move.
There are, undoubtedly, actual Catholics who are seduced into imagining that the SSPXers are being treated "uncharitably" when charity or love requires NOT that we tell the excommunicated schismatics what they WANT to hear but rather what they NEED to hear. Despite their sulfur and brimstone, full speed ahead!
Hi-HO!!
