mchael, answer to your statement is very simple. you must be working in a company. How many times, the chairman of your company comes to you and listens to you!!!! because, their are other seniors to whom you chairman listens or if you are on a senior post, then your boss is biased and so he listens to someone else or he has some chamchas with him round the clock.
once everyone get freedom, then ever person starts making his presentation. in this scenario there are more fools who shouts and project their views and their are few genious and experts , who too get chance to put their thought process. Dr. Purkaystha is one of integllegent scientiest who never got chance to put his view infront, or his voice was suppressed by some chamcha type of senior scientist.
