Hmm, you were right, if one is famous and doesn't impact the society in any good way then he or she is of no relevance.

I am not also a die hard fan of any celebrity though I like a few too. The persons you mentioned really caught my attention especially the one that was shot dead. Normally, people who say the truth don't usually last. His killers might think they succeeded, true he is dead yet he lives because his messages will never die.
