Well as we know, the biggest enemy of a traditional Catholic is... other traditional Catholics. 
As someone who holds the sede position, I'm very disappointed in some of the sedes commenting in this thread. Sean Johnson finally comes around to the sede position, and the first thing that some people here can think of is how he should come back here and grovel at the feet of the Sede Sanhedrin in apology, all because he has changed his position on the crisis in the Church to the position he used to argue against. I completely understand Sean not wanting to come back here to post if this is the kind of welcome he would receive.
While I appreciate the generous, even noble, spirit of your view, I think fairness requires a look at the other side of the coin too. Those calling on Sean for an apology have had years of experience with him, years worth of, lets be honest, jackassery. It's easy to see and to say that others should just forgive, and, honestly, that is the right answer, but its not so easy when you're the one that has to do the forgiving. What I'm saying is to realize that many of the enmities found here aren't based on one-off events, but are cuмulative. It's the same thing with Lad, he's worked very hard at creating ill will towards himself for far longer than the recent political debates and that's not anyone else's fault but his own.
As for Sean, I only had a handful of run ins with him for which, to his great credit and to my edification, he apologized. I commend him for his virtue and am glad to hear that he is still working out his salvation.
