This is pretty accurate, but it should be noted that ALL ideologies can be and often are treated essentially as religions.

They all serve as dogmas and myths around which a set of true believers congregate, who then alternate between telling each other their myths of inherent superiority, proselytizing non-believers and lashing out at the followers of competing sects. They all lay out moral guidelines by which they can both affirm the faithful and condemn the heretics and unbelievers. They all demand absolute submission and attack any sign of deviation, and since they've defined themselves as inherently morally superior, they consider any of those attacks to be self-evidently morally justified. They all have a hierarchy (whether formal or informal) by which dogma is disseminated to the faithful, with the view (again, whether formal or informal) that ideas that have not been sanctioned by the designated people somehow don't qualify.

And, pointedly, they all have their own "Satans" - the ideas and/or people that they can generally be counted on to blame for whatever evil might arise.
