Why are you bent on proving that they don't care to reply out of arrogance? Why don't you sit down and think the reasons that could be behind this? Is it not possible that they are not very technology savvy and do not check emails regularly? Maybe they do not have proper internet connections and rely on others to forward emails to them. And when they do check their inbox after a gap of some days it must be filled with hundreds (or even thousands) of emails! Is it possible for them to even read each one of them? If some of the ulama have managed their work so as to give equal importance to emails this is very good but it does not mean the others do not care to acknowledge. Go meet them once and ask a question, if they don't care to answer then come back here and highlight "that many 'Ulamah in general do not reply or even care to acknowledge a question." They haven't take money from you so that it is mandatory for them to reply to all of the emails they must be getting every hour. Then why don't you give your own opinion as to why they don't reply? Do they think they have got too much of this ego thing? What exactly do you want to imply?
