I think certain German bishops and other publicly heretical bishops in the world should be excommunicated as well
I have no problem with the excommunication of the SSPX, I indeed think it is just. They didn't necessitate to consecrate new bishops, they did it anyway, this is a clear schismatic act and excommunication latae sententiae is the right answer.
In the meanwhile, German bishops and other bishops that support progressive stances as female priesthood, homosexual sacramental marriage, permitting contraception and pretending sin and devils are overpassed concepts, all in the name of "the spirit of Vatican II" (though Vatican II never contradicted tradition about those topics) are doing the exact opposite: SSPX acted schismatic while being theologically orthodox; progressive bishops keep obeying to the Church while professing heresies, which is a form of schism. Both are unacceptable positions, but the Vatican only excommunicated SSPX. I am not to say to the pope what he should do or not, but this is my humble opinion.
