SSPX hit jobs aren’t a new phenomenon around here. Many of those links you post point to articles written by the leftist religious equivalents of the Southern Poverty Law Center. The SSPX position on the subject of “anti-semitism” is that they are opposed to it. Some of the statements that have been made and highlighted in these articles are taken out of context and deliberately translated incorrectly (sound familiar?). The actual SSPX positions are exactly inline with historical Catholicism. My own interest in the SSPX is the correct and valid liturgy, which you also find in the FSSP, and the “extraordinary” form.
There are still copies of the following neo-Nazi SSPX publication on websites (most of the sites, trashy). Nothing was really hidden.
