What it means is that if you are going to condemn the "disobedient" Catholics who disregard Ecclesia Dei's call for "ceasing their support in any way for that movement.";
you also must condemn those hundreds of bishops who do not provide "a wide and generous application of the directives already issued some time ago by the Apostolic See, for the use of the Roman Missal ... of 1962."
Ecclesia Dei calls for both of these things. You can't take the cafeteria approach. Either accept all parts of the encyclical or not.
Is your bishop one of the hundreds who do not provide "a wide and generous application of the directives already issued some time ago by the Apostolic See"? If so, do you support him in his disobedience to papal authority?
My point is that there are worse problems out there than the irregularity of the SSPX folks. Too many of our own bishops have done to our liturgy the same thing that they have allowed pervert padres to do to our children.
