It feels like I'm getting mixed messages about trusting the science. Some science is apparently double-plus-good, and some science is double-plus-ungood. I'm not sure I understand in advance which science is permissible by the Inner Party.
To clarify, it seems like you're arguing a strawman (or strawwomyn) argument with your (IMO very bad) points.
To pick a less contentious example, I think science can clearly recognize that the average man is a little bit taller than the average woman. Would you agree that this is correct? In and of itself, would making this observation be bigoted?
It doesn't seem to me that doing the science and objectively recognizing that this height difference currently exists in nature is bigoted against any group. To me, it would take something akin to a law that treats people with different heights differently in society to turn a scientific observation into some kind of oppression or harm.
