What I certainly do understand, (and which is plainly evident) is that regarding responses to conflicting comments by astronauts and scientists, there is much rationalisation.
The word "rationalization" (American spelling) implies explanations that are false. What, exactly, is false about our explanation for why stars are sometimes seen in space with the naked eye, and sometimes not?
Here, I'll give you some possibilities from which to choose. I can provide a list of relevant research material on request.
Does the human eye not have a very wide dynamic range, with the retina reaching full sensitivity to dim light only after minutes of slow chemical adaptation in the dark?
Do the Apollo spacecraft cabins (CSM and LM) lack bright white cabin lighting that can quickly reverse this chemical adaptation, i.e., kill night vision?
Do the Apollo spacecraft have large picture windows giving a panoramic vista of the celestial sphere that would make star sighting easy?
Were the windows on the Apollo CSM always unaffected by outgassing, escape tower solid rocket plumes and other problems that impaired visibility?
Did the Apollo astronauts land on the moon at night when stars would be easiest to see?
During their lunar EVAs, did the Apollo astronauts use highly transparent visors?
Was stargazing with the naked eye an official goal of any Apollo mission?
If "no", did the astronauts have plenty of spare time on the lunar surface that they could have used for stargazing?
This should get you started.
