That could be. Doctrine is a pretty wide topic. There are probably doctrines I don't know anything about, but I do feel there are at least some doctrines I know at least some about.
Know at least the basic idea I think thats good enough to at least comment on the subject?
I have hardly seen anyone on this site use scriptures to back their arguments up. That means that it's almost all opinion. As long as people are putting up their opinions, there will never be a worthwhile discussion on this site. You really do need to know the doctrine before you can say anything useful about it. Anyone who disagrees wiht me doesn't know anything about church doctrine.
