it is unclear who this comment is directed towards though.
I don't personally really have anything against religions in general though, if that is what you mean (*1).
but, I don't necessarily have a particularly positive view of everything in-general though, and systems of authority are very often abused.
but, I am less inclined to give specifics here...
but, yeah, a religion doesn't really need a hierarchical organization or centralized leadership (and many religious groups exist just fine without them).
(and, admittedly, I am not really a fan of aggressive proselytizing either, ...).
it is basically much like how generally things like markets controlled by a single company, or governments ruled by a single "absolute" ruler, are generally things to be avoided. it is better when there is a freedom of choice in these matters.
so, similar sorts of problems...
ADD: people don't all have to agree to achieve harmony, and expecting everyone to agree on anything is unrealistic. however, people also need to allow a little flexibility, for each person to believe what they believe for themselves.
in my case, I also have some potentially non-standard and sometimes controversial views, as well as there existing a sort of split (on religious grounds) between my immediate family and extended family. actually, if one goes out a little further, there is a split again (so, most of the more distant relatives are yet another religion). well, and on the other-side of the family, yet another split, and another religious split.
the result is around 5 religions over 4 generations, and a lot of relatives with uneasy relations.
(and, throw in some ethnic controversy as well, ...).
*1: note: I do consider myself a Christian, but I am also non-denominational.
then there is all the usual doctrinal fun, a person can maybe debate whether or not I actually classify, but oh well.
but, of note here (related to some of the above): Matt 20:20-28 (specifically 25-28), John:18:35-37, ...
