In this case there are observations made and conclusions reached based on a scrutinized theory, so it's nothing like a cult.
A cult is a bad comparison because there is nothing real being observed. Here we are giving subjective impressions on something which is objective. If there is a general consensus, assuming it isn't a matter of chance, you can reasonably assume there is something objective about the consensus.
Stereotypes.. they are useful. The most secure airport in the world accomplishes this through an elaborate system of stereotypes.
