No, Alecto, you're correct. The "why" is in fact more important in some ways than the fact of the 'victory.'
We should have a society that does the right thing because it's right, rather than because of self-interest. Progress towards that end is slow and takes lifetimes.
And no, I totally Don't Get why that should be.
Never linger too long with the ignorant,
throw stones at their talk.
Walk only with the lovers,
the mirror of the soul gets rusty when
dipped in muddy water.
