Your comment seems to me to assume that Scott thinks there would be nothing very wrong with a definition of “fish” that included whales only because that’s something he has to think in order to remain consistent while classifying transgender people the way they feel they should be classified.
Believing things for multiple reasons is a thing (despite the LW idea of a true rejection, as if people only have one reason for everything). Moreover, people aren’t perfectly rational machines, and motivated reasoning is a thing. I certainly think that needing to believe it for the sake of transgendered people is a large component of why he believes it, and that he probably wouldn’t otherwise believe it, even if it’s not the only reason why.
I agree: one can have multiple reasons for having (or professing) a belief. For that reason, to me saying “X believes Y because Z” (where Z is a disreputable reason and one would otherwise assume something less disreputable) is rather uninteresting if not accompanied by actual evidence that the other less-disreputable reasons aren’t sufficient explanation for X to believe Y.
In the present case, Scott is known to be a good thinker, and has given (not particularly disreputable) reasons for believing Y; rationalists on the whole are also pretty good thinkers (Nate and Eliezer included); if you think their opinions on this point are mostly the result of political prejudice, you’re entitled to think that but I don’t see any good reason to agree.
