If you categorically define an ideology to be a system of pure concepts, independent of any practice of thought, speech, or action by a professed adherent, then you will inevitably see it as a category error, yes.

(You'll also have a hard time enumerating those concepts in a complete and consistent way)

But if you're even a wee bit of a subjectivist, as many (not all) social scientists and social philosphers are, then a definition like that isn't interesting or productive. From that perspective, ideologies are something that people profess adherence to and express statements about and behave in self-identified accordance to.

They gather in elections, they discuss power through the lens of capital and labor, they recycle or avoid eating meat, they recoil at government overreach, they expose fraud in purported miralces, they pray, they trade trolley problem memes unironically, they protest against inequality, etc

If these don't make sense to you as "rituals of ideologies" for people doing cross-cultural studies, that's fine, but then I have a sense that a lot of cross-cultural studies just feels like hogwash to you anyway. I doubt I could change your mind here. :)

Well, you're right about that. I suppose I don't see the point in calling what you're describing an ideology. Just call it something else so ideology can mean what it means to everyone else..? I see all your examples as like, social behaviors that happen to presently align with the ideologies. But in the past or future they won't, while the ideologies will persist, cause they live in 'idea space'.

(nor would I call any of those rituals, either, but I guess words don't mean what they normally mean in those fields)

I figured!

If you earnestly wished to "see the point", you're tripping yourself with by taking for granted "what it means to everyone else.." and things like "living in idea space"

There are traditions of study/thought that use ideology the way you mean, and traditions that don't. The variety of use is well-represented and has been since the word came into use. Likewise, "idea space" is a specific concept that some people accept as sensible and others don't. Again, the variety of relationships to it is well-represented (and stretches back millennia, on that one).

You can actually see an example of this kind of differing-perspectives-in-wide-use in the way use used "the moral basis of Christianity but not the religion itself" in your own comment above. While Platonic ideas predate Christianity and have much influence on its shape and study in the West, the that statement would strike most traditional and many modern Christian thinkers as non-sensical. To them, there is no sensible separation of Christianity's "moral basis" from its Church/people and trying to make some distinction is as alien and "pointless" to them as different senses of ideology are to you.

And yet, of course it's interesting to think about Christianity's "moral basis" as an ideology existing in "idea space" because it lets you relate that part of Christianity to other things that you feel are comparable using techniques that you know how to work with and have confidence in. That's pretty much exactly what's going on with social scientists/philosophers who think about ideology in the way I've been describing above.
