That's a good question - though I'm not sure I can think of a good answer.
I know that, in most of my writing, I tend to use 'they' as a gender-neutral third-person singular pronoun... when I wrote 'Man is a rational animal, etc', I was aware that I could have rephrased the whole thing to be gender-neutral... but when writing, I felt that it wouldn't have provided the same feeling - short, sharp, direct, to-the-point. The capitalized term 'Man' is, for good or ill, shorter than the word 'humanity', and "Man is a rational animal" has a different sense about it than (I wanted to insert 'the mealy-mouthed' here, which isn't a term I remember actually having used) "humans are rational creatures".
There's probably something Dark-Artish in there somewhere, though it wasn't a conscious invocation thereof.
Politics is the mind-killer; but rationality is the science of /winning/, even when dealing with political issues.
I've been trying to apply LessWrong and Bayesian methods to the premises and favored issues of a particular political group. (Their most basic premise is roughly equivalent to declaring that Iterated Prisoner's Dilemma programs should be 'nice'.) But, given how quickly my previous thread trying to explore this issue was downvoted into disappearing, and many of the comments I've received on similar threads, I may have a rather large blind spot preventing me from being able /to/ properly apply LW methods in this area.
So I'll try a different approach - instead of giving it a go myself again, I'll simply ask, what do /you/ think a good LW post about liberty, freedom, and fundamental human rights would look like?
