Extremism in thought

Tell me now!!! Do you belong this OR that????
call it the "OR syndrome", "being extremely clear", "having strong opinion" etc etc. The root, for all these states of mind lies in their, what i call, Extremism in Thought. Somehow i feel, that the best things in this world come from convergence of two paradoxes(ugh!)..its like this we SHOULD have social workers who are "selfless", "altruists" , "not for profit" etc etc. we SHOULD have a business man who is "selfish", "greedy for money", "profit oriented". So these two ideas emerge from the OR pardigm.

Now, why cant we accept a selfish business man for whom ther is no space for a new penny in his wallet and wants to drop it to a cause rather than throw it... IS IT UNACCEPTABLE??? I think this is AND paradigm whcih gave birth to concepts like corporate social resp etc etc. doesnt it make sense to create wealth and distribute it rather than ditribute a scarce resource.

Coming back, sometimes the strength of ur expression about one subject is considered to talk about ur confidence-again roots in extremism in thought. cant I be open enough to accept changes to my so called deep-rooted opinion. does this speak of low-confidence and in turn lesser knowledge or clarity? As per Carlos Castaneda's don Juan's Teachings (google it, i read it only once), after fear, Clarity is one's own enemy....so i feel we need to be less deep rooted about opinions.

this is a larger concept which can be extended to many states of minds and popular thinkings.say like "regionalism", "religionism", "casteism" anything which makes you a strong follower or subscriber of one thought, one way of life or one opinion, which I think makes you a very very small person and hinders you to grow as an enlightened being...
what say dude??? for understanding (better) what i'm blabbering read the poem "IF" by Rudyard kipling.
