Au contraire. The liberals in the hierarchy can't arbitrarily excommunicate SSPX priests (although it is clear some would like to) because they are not schismatic, so they have done the next best thing by contriving to make the status of these priests so ambiguous that many Catholics fear any type of association with them.
Meanwhile, purveyors of Masses such as the one I was forced to attend while on travel (rock band set up directly in front of the altar, men in grubby shorts and t-shirts blaring hideously ear-splitting racket that was a cross between a mariachi band and the Grateful Dead while deafened parishioners cringed in their pews) receive unquestioned support from the same liberal hierarchy which holds all traditional Catholics (including the SSPX) in clear contempt.
Would a conscientious parent expose children of tender years to the institutionalized resentments and rebellion of the SSPXers? What was that portion of the Act of Contrition about avoiding the near occasion of sin? Maybe if the SSPX priests accepted being gagged and muzzled and prevented from preaching, it might be different.
What will happen as the current SSPX bishops die off? Will the "emergency" continue to justify the consecration of replacements without jurisdiction to satisfy Marcel's theft of the ecclesiastical goods of consecration without obedience and without papal permission? Are we in for another "Old Catholic" ongoing schism that seems to be its own excuse?
Saint John Paul II seemed to have no problem, along with Cardinal Gantin (neither one any kind of liberal) declaring the illicitly consecrated Econe bishops of SSPX to have committed an act of schism and to excommunicate the lot of them. Unfortunately, the excommunications were lifted by Benedict XVI and for his efforts at "reconciliation," Benedict was spat upon by Fellay and company in their never-ending contempt for actual Church authority. Benedict would simply not submit to Fellay's "authority." Talk about putting the cart before the horse!
Do the SSPX priests obey Fellay or the Vatican? In obeying Fellay, are they not ratifying the schismatic act of Lefebvre, de Castro Meyer, Williamson, de Mallerais Fellay and Gallerata? Establish mandatory loyalty oaths for all priests and watch the bad and rotted fruit fall from the tree. And not just SSPX either. Turn then to those in the pews. Rinse and repeat as necessary.
Give any SSPXer a doctrinal exam and a few pointed questions about the authority of Saint John Paul II as Supreme Pontiff and it will be readily apparent that excommunication is not arbitrary. Those who exercise their "catholic" faith by expressing their naked contempt for papal authority are not "traditional" except in the worst "tradition" of notorious heretics since time immemorial who, if they continue to CLAIM to be Catholic, deserve a lot harsher treatment than excommunication.
