“Is it possible to fight tenderly for beauty and truth and love without despising those who spread ugliness and lies and division?”
It seems clear to me that Truth is almost certainly illusion, and that truth is more of a best guess than any sort of absolute.
It also seems clear that beauty is a matter of personal choice and preference.
It seems that love is, at the deepest of levels, a commitment to life, to liberty, to cooperation, with all the awe, respect, acceptance and humility that must come from such things.
It seems that one can value life and liberty and integrity (in so far as integrity is our best model, our best guess, based upon all levels of available evidence and interpretive systems), and in those values can have compassion for those who hold other values, and must be restrained as a result of their threat to the lives and liberty of others (acknowledging that much of what we are is a matter of circumstance, and in different circumstances we could easily have become them).
