There are two conflicting assumptions here:
1) That a woman having an orgasm from rape is in no way related to her mental state.
2) That the above assumption is false.
Seriously, don't use Occams Razor if you don't know what it means.
Assumption 1 is an original assumption. It relies on an entirely new logical infrastructure to sustain it which is not well integrated into current understanding of the topic. Even the people who do claim (anecdotally) to be suggesting that orgasm does occur during rape are suggesting that it is not voluntary. You are making this assumption from nowhere, and it contradicts the vast, vast majority of established information.
Assumption 2 is not even an assumption, it covers a whole range of assumptions from across the board of existing understanding of the topic. It is the existing rule, it is sustained by tested logical infrastructure.
As said, Occams razor does not determine truth, but it is a good model to allocate the burden of the proof, and the burden of proof must always fall with the original assumption. A nuclear engineer doesn't get up in the morning and decide that the power plant he works at is powered by magic, the established assumption carries the most weight. Anyone who wants to claim that the power plant is powered by magic recieves the burden of proof.
It has yet to be evidenced to me that women do orgasm during rape. I cannot find a single reliable study suggesting it, just a bunch of anecdotal evidence. That evidence is hard to ignore, true, but a consistent point comes out of it. The people who experienced it did not want it. It did not bring them pleasure or joy. It is always described as unwanted physical arousal, as a betrayal of the mind by the body, or in similar terms.
Actually, the most common answer to the question of why this happens in the anecdotal cases is not that it represents not a voluntary desire for the act, but rather a bodily defence mechanism. This implies (with reasonably sound evidence from anyone who has ever got turned on) that the components of the response cycle are in some way linked, so in order to loosen or lubricate the vagina a person has to become aroused. If they become sufficiently aroused, they may orgasm. Forced penetration of the vagina is extremely painful and physically damaging, it may well be that the autonomic response is to attempt to lubricate the vagina, which may result in physical arousal.
That is an assumption. However, I'm inclined to take it infinitely more seriously than yours because it depends on fewer original assumptions to sustain it. We know that rape is terrifying, we know that it is painful, we know that it causes immense physical harm. We do
not know of a correlation between light D/s practices and rape. Occams razor that.
