"It is absolutely true"
Nope, sorry. Hating Satan's modernism is not hating the Church, even when modernism infects her.
The sspx is no different than Luther, and Calvin and all the other enemies of Christ and His Church.
And only a soi disdant trad could claim evil good.
There has NEVER been a time in the entire history of Holy Mother Church, NOT ONE DAY, where a schism has been defended by members of the Body of Christ. In indetifying with the sspx, in supporting it, one identifes they are outside the Chruch and they must prepare themselves to suffer the consequences of dying Extra Ecclesian Nulla Salus.
