I don't dispute there are issues or differing points of view. I personally see the ναccιnє as a form of human sacrifice, but I can also see the point of view of those who allow it based on Traditional Catholic moral theology.
That's the problem with Resistance type people. They unjustly make the SSPX out to be no different than say EWTN or your local Novus Ordo diocese when in reality and in charity such a conclusion is absolutely ridiculous.
If we criticize the SSPX, it's because we expect more from them than we do from say EWTN or the local Novus Ordo diocese.
