Christianity is heading for a full allegorization

[Angrboda]

Strictly speaking, everybody has an ideology, except for the fact that the word is not often used in that sense in colloquial discourse.

I wouldn't say so. Belacqua claims that trusting science is an ideology. But science is evidence, and there is no ideology of evidencism.

Science is many things, but it is not evidence. Scientific practice may use evidence or embrace philosophies that value evidence but science is not evidence itself. And yes, evidentialism is an ideology, being the set of beliefs and propositions that hold the proper place of belief rests upon things having the right sort of evidence. You want to try to make science some sort of neutral, objective thing through contorted language and conflation of meanings, but it is not. I can only suspect you want to do this because you think that doing so can render it immune to the sort of criticism to which ideologies are subject. All you've shown is that you can abuse language. Science readily becomes an ideology such as under the influence of the Vienna Circle in the early 20th century wherein the type of philosophical standards and values was enshrined as ultimate truth in what came to be known as scientism. You seem to embrace scientism yourself by trying to distinguish scientific values and philosophies associated with science as being somehow independent from, and uninfluenced by subjectivity, thereby rendering it some kind of superior standard. That is pure scientism, a form of worship of science. The only problem is that it cannot be defended logically and leads its proponents to saying stupid things like, "science is evidence."
