It might be stronger if there is no proposed mechanism for denial / false memories, and you're just being accused of lying, perhaps?

Maybe, though my purpose was to minimize your own reasons for being convinced of your own innocence. If other people are accusing you of lying, well, you know you're not lying, so their accusations do not act to reduce your own basis for your convictions.

If we want to draw an analogy here between the innocent framed person and the religious person, we might compare the proposed mechanism for false memories with the mechanisms that the non-religious propose to explain why the religious believe what they do. For example, an atheist might say, "you only believe that because you were taught it when you were too young to resist indoctrination". A psychologist might come up with an equally plausible explanation as to how you came to have a false memory of your innocence. In both cases, you (the religious person or the accused person) have these explanations purporting to explain and debunk your beliefs that you need to deal with one way or another.
