call me cynical, call me a man of anger and pessimism, but the problem i have with peoples overwhelmingly positive response to this is that THIS. CHANGES. NOTHING.
The very nature of speeches like this make them ineffective. Mankind does not change by choice, they only change by forced necessity (see human history for evidence). So i the lonely cynic ask you instead of "What will you do to change the world?", I ask "WHY WONT YOU?"
