This is a prime example of my point that you do not present a rationale, but rather provide the assertion as self-evident. Your statement that others' beliefs are long-held but unexamined or unquestioned is an attempt to cast the opposing opinion as uninformed, which consequently means that yours is the only informed opinion.
