And all those millions of Catholics who believe in contraceptives, civil gay marriage, women priests, and all these discussions on so many "settled" subjects, including infallibility?  You are saying they are not Catholic? 

Much is being called into question.  The issue of the "authority" of bishops and popes is being questioned around the world.  Being Catholic is no longer tied to something like accepting that "infallibility is a dogma of the Church".  Not even calling oneself "Roman Catholic" is tied to accepting a doctrine or dogma of "infallibility."  

It is getting interesting to be a Catholic.  We have to use our minds - not to memorize and be able to spit back out what is learned by rote.  No.  We have to think, use sources of information we never used before, be willing to doubt as well as be willing to believe.  Recognize new knowledge, new ways of being community.  Pretty exciting stuff!

Tri, being "Catholic" is not either/or.  It is both/and.
