That's because there is no such thing as "secular ideology". It's a meaningless phrase.
There is no such thing as "secular ideology". There are many. Just as there are many religions.
There is materialism+work ethic, there is materialism without work ethic, there is "wokeism" (to pin a definition, the belief that oppression is a fundamental societal force and clearly directional based on some enumerated characteristics), there is nationalism. There's even "startups" :P
But perhaps you have a grain of truth in that rarely is a "secular ideologist" a "monotheistic" (monoidealistic?) one. Usually one's identity holds a plurality of those identifications.
Also, people can have a strong identification to ideas without a community to back it up (another grain of truth, and the saddest part)
Overall the point isn’t to say that all secular belief is the same. The point is that any secular ideology you follow will have the same characteristics of religious belief despite lacking definition.
Yes, there is no such thing, but it does not become meaningless, and so such be called 'something'
It is the opposite, the repudiation of 'religious ideology'
just like there is no such thing as 'cold' - it is the opposite of 'heat' which is measured, but 'cold' as such, holds some value in dialogue, so it is for 'secular ideology'
As in it's equipped me with mental models to understand which components of secular life are acts of faith & ritual vs reason.
> 'secular world' is perhaps not as centrally organised as you may believe or wish for
Nor is it uniform. But there are some overt and some covert aspects. the covert forces benefit from being nebulous.
One reason religions are so open to attack is that they have a clear identity and value system (not necessarily good, but at least clearly stated). If you think about it, you can have a healthier relationship with a religious opponent– as long as you have equal power, you can oppose each other in a healthy way.
The secular world is applying all sorts of demands & social pressures on you, and there's no way to oppose them, because secular ideology doesn't have an identity, an institution or value system open to attack. It's like fighting smoke or a swarm of bees.
