You are obviously ignorant of SSPX and are simply repeating nonsense. The typical SSPX parish is no different from any pre-Vatican II parish. I know, because my family attends an SSPX chapel. The priest is a good young devout and devoted man. He is cheerful and commonsensical--and hard-working.
I'm unconcerned whether your priest is cheerful or glum. I'm acquainted with many modernist heretics who are equally as cheerful. It means nothing.
As for my familiarity with SSPX, I read the writings of its ambassadors and apologists. That includes you. So if I've been deluded into thinking that SSPX is a little extreme, then take a bow my friend.
The incessant and uncharitable insults directed toward the Holy Father do not convey the aspect of a reasonable group of people. Just because I haven't been to your church does not mean that I'm unfamiliar with your organization.
Ask anyone who reads these boards. Writings from a good number of SSPXers, read over a considerable period of time do enable one to construct a picture and get a feel for exactly what you're all about.
