Present humanism respects caste system and human races but "not CASTEISM and racism". True sense of.caste system is often misunderstood as "divisive-mindset". But true-sense of caste system is to make evil self-divide by itself if we are able to include other's caste. Hindu MARRAIGES need respect "caste system between bride and bridegroom" which is nothing but "compatibility". If there is no compatibility between bride and bridegroom,marital disharmony creeps sooner or later. So only for purposes of MARRAIGES,caste system of true-divisive-mindset is to be respected. We are not supposed to encourage quackery of mind compatibility. Isn't it ?
