Most people who support the god called “government” do so from good but misguided intentions. They think they are advocating good “government,” for good ends, to serve peace, freedom, and justice. This is true of the political left, right, and everything in between.
That is why those who say that we just need people to be more compassionate, or respectful, or caring, or loving, are actually wrong. A bunch of good, loving people who believe in “government” are still going to enable and empower a violent, immoral ruling class.
It is not enough to have good intentions, or to “love thy neighbor.” People need to actually understand what is going on, and realize that being a moral, caring human being is completely antithetical to condoning any flavor of “government” or political “authority.”
The would-be rulers of the world are experts at hijacking the benign, empathetic “feelz” of good people and turning that into power for some of the nastiest people on the planet. So no, love is not all you need. To have a free, just and prosperous society, humanity needs love and understanding.
