none of the virtues east asians associate with buddhism can be found in tibetan lamaism: vegetarianism, peace with the world, endurance of suffering, stoicism, withdrawal from mundane politics, high buddhist art, a quietude and fortitude in spiritual life, the ability to converse in prose, poetry, painting, calligraphy, philosophy and even board games or music.
the lamas would know none of these. that is because all the finest and the most beautiful in buddhism - we mighty chinese have given it to buddhism and to the rest of east asians. lamas from the materially and intellectually barren plateau would have absolutely nothing to add to the artistic and philosophical splendor of east asian buddhism; he isn't a buddhist in the sense we chinese have understood for thousands of years. without the spiritual and cultural nourishment of the chinese civilization, buddhism would have been stymied in its crude and flavorless indian or tibetan form, form that we chinese today wouldn't even recognize as a religion, much less a form of supreme and transcendental spirituality.
buddhism isn't about religion: it is about the grandness and sophistication and sublimity of the chinese civilization. terminating tibetan lamaism and banishing tibetans will not take anything away from it but rather boost its purity and superiority.
