"Insistently believing that this is a photo of Neil Armstrong in the face of everyone else's..." Can one really insistently believe something?

The sub-context is that there’s an iconic photo of Apollo astronaut Buzz Aldrin on the Moon taken by a large format Hasselblad camera and in Aldrin’s gold reflective visor one can see the photographer Neil Armstrong in their space suit. Though the image is pretty small one can recognize the details of the suit, the camera being held, and through a process of elimination can determine which of the two astronauts it is.

Please let us not debate under this question post itself if the photo can or can not be characterized as a photo of (among other things) a photo of Neil Armstrong. Passions tend to run high when I suggest that it could be characterized that way.

Here I’d like to consider if a phrase that turned up in comments reflects a proper usage of the two adjacent words.

Insistently believing that this is a photo of Neil Armstrong in the face of everyone else’s description of the photo as one of Buzz Aldrin that has a small reflection of Neil Armstrong, is the classic definition of dogma.

Question: In this sentence should "Insistently believing that…" be taken as an assertion that I am "insisting" upon something simply by "believing" it? To me there seems to be some fundamental dissonance, that the mere act of belief and absence of a "you’re right, I’m wrong" is the same as insisting on something, either that the existence of my opinion is an act imposed on or statement made to others, or my failure to yield is.

Can we use these words in this way and be faithful to the range of definitions and usages they are understood to span?

For further context and background relating to the phrase’s genesis:

• Space SE: Lot 345 of Christie’s “Voyage To Another World” auction supposedly has the only photo of Armstrong on the Moon, but isn’t this one also?
• Skeptics SE: Is there only one photograph of Neil Armstrong on the Moon?
