i didn't know buddhism so little.
but anyway, it's not exactly accurate. because christianity also
have abit of disagreement due to theological differences.
like majority christians believe that mormons, jehovah witnesses
etc are all cults.
the mainstream ones are catholics (again, differing views),
protestants (methodists, brethern, lutheran, presbyterian,
anglicans..)
but basically so long as a church believes the truth which comes
from the written Word. and not add chilli and pepper to spice up
the word, it shouldn't be a cult.
so roman catholic is a cult to you?
