"Global citizen" he is not, no one is. I know exactly what Obama meant by "active citizenship", and it is far from anything to do with "co-operation and consciously evolving" or "Being generous, being kind, being aware, being positive, being interested , and being active". 
If you haven't learned in the 8 years he was president that what he says, what he means when he says something, and what he does are all different things, then I can't help you.
