This might shed some light on that:

I am one of the few sedevacantists on this site (and treated as a non-Catholic for that), but there MANY Catholics who are sedevacantists.
Well, at least you're honest about this. Many of your fellow RCs on these threads certainly act like they're a sedevacantist!
Thanks, that was very helpful
The technical definition of a sedevancanist is one who believes there has been no true pope since 1958. I believe Benedict is the true pope and Bergoglio is illegitimate, if not the anti-pope.
To compound my personal difficulty, I converted to Catholicism when JPII was pope. This Bergoglio mess isn’t the church I converted to.
