Being Mevatel everything outside of the Torah

Being Mevatel everything outside of the Torah
The biggest criticism I have regarding the chinuch that I received in my b'h lengthy Yeshiva days is that which we where taught to be mevatail and denigrate anything outside of Torah and the Torah world. It is such a jaundiced and dangerous outlook! Any criticism of our community, no matter how valid, was always viewed as an attack that must be defended by going on the offensive to show that, pum fahkehrt, just the opposite, the criticisms of our critics shows their krumkeit. As by definition, whatever we do MUST be right and correct.A particular danger of this approach is that we lose the advise of 'chazal' of 'Eyzehu chacham halomeid meKol Adam'. Since we are not perfect, we lose the ability to improve ourselves by accepting valid criticisms and by seeing what other's are doing right.A Rebbe of mine (who I still love and respect) once during a shmooz, was very critical of noted humanitarian (Dr. Schweitzer) who raised money for his clinic in Africa by giving concerts around the world. My Rebbe claimed that he could have spent the whole year giving concerts which would have raised more money to send 100 doctors to Africa - but he wanted to be the hero doctor, so he would rather stay in Africa most of the year and fundraise just to support his clinic. He attributed this to Gayvah.The criticism might be correct - but does this make Dr. Schweitzer worse than the rest of us who just stay home and do nothing? Not raise money nor go and heal people? So instead of looking to Dr. Schweitzer as a source of inspiration, all we are left with is denigration and no chance for inspiration to follow in his footsteps (or those of the famed Dr. Wallach of Sha'arei Chesed hospital.)
