I would certainly agree that some cultures are better than others. Anyone saying otherwise is delusional. This is simple due to the fact that differences necessarily have different values. The obvious difficulty is measuring differing items against each other and this is why many abstain from commenting.
Whether the "Western" traditions are better than others is open to debate. Overall, I think yes. In many ways other cultural attitudes surpass more Western ideals. Undoubtedly there is an exchange where one set of views benefits another and so they assimilate or replace.
All cultural traditions have certain political prohibitions and taboos. Where the 'better' cultural traditions seem to excel is in how the breaking of these 'regulations' is handled.
Societies that expel or annihilate those speaking out against them generally fall. We need a Diogenes or a some form of courtly jester to humiliate us. I leave you with a poem I wrote some years ago:
Rompa Stompa
Aristotle chortles mimetic
a parody of a witless lick-spittle lampooned
comedy sculpts its laughter crafter
un-mastering the mastery of the masterly majesty.
Jesters gesture to the King
satire dripping they prance and fling
their sullied words in simian farce
un-mastering the mastery of their masterly majesty.
Chaplin clowns around his silent circus
flagellants of foolery slapped with wit sticks
raucously erupting Bacchus takes a bow
un-mastering the mastery of our masterly majesty.
Heads crack open with screams
beams split faces bringing to knees
the lesser man mocked and defrocked
un-mastered the master is regally flogged.
