I see what you are saying and it is mostly true. However, in my opinion, a believer ought to have sufficient knowledge of his faith (especially if he joins forums wherein he is going to be asked to talk about it). Secondly, converts especially should do a lot of research before converting to be able to provide at least reasonable claims why he converted and what he believes and why. The believers should do thorough research in-stead of just relying on what Priests, Gurus and Imams say and taking it for granted. Also, one could go to several different, say, Priests and get several different answers. For instance, does one go to a Roman Catholic, Eastern Orthodox, Protestant, Anglo-Catholic, Lutheran,or a Baptist priest/vicar/whatever?
Of course, I agree with you. But a convert should convert to a faith when he or she has enough evidence for oneself to accept it or simply feels like that is correct.
One goes to the priest of the branch he wants to learn about, simple.
