1) I've been a Catholic for nearly 74 years and absolutely disagree with "changelessness" as being a "central tenet."  The "central tenet" of the entire universe is CHANGE; annihilation is the consequence of NOT changing.  (Check the evolution of doctrinal truth as it changed over the centuries, beginning with the Council where the principals VOTED ON the divinity of Christ.)
2) I deny nothing of the essentials of the Catholic/Christian faith.  I certainly DO have serious objections to the laundry list of evils detailed in my original post, and I have to ask why you DON'T? Take off the angel-dusted blinders you're wearing and view the institutional Church objectively, then ask if you support those characteristics that originate from corporate sinfulness. 
3) I'm sorry if you are offended by those of us who are not blind to the changes that must occur in this institution.  We are a small, vocal group whose opinion doesn't matter in the long run.  You don't have to read this forum.
