Re: Why is it bad?
Well yes. You are talking about ideology preference. Not about anything intrinsically evil going on.
I say: we protest when it happens. I won't be protesting though.
Also... micromanagement is not necessarily effective. Simply because the world cannot be divided into small communities forever. There must be a general direction in which humanity is going.
Therefore eventually someone will have to redirect all the diverging communities, to focus them in the same direction. Otherwise there will be no progress... And what about war... One world government prevents war.
