He is a dangerous, utterly toxic creature who has ZERO qualms about destroying peoples lives by fomenting chaos and confusion, and blueprinting the destruction of the worlds vulnerable democratic governments. He does so by amping up the WORST aspects of the human personality: blind hatred of the other, anti-Semitism (globalists, as used by David Duke and Alex Jones), militarism, and destruction, in this case, of checks and balances, transparency, and stability.
Bannon, doggedly pursuing what he terms deconstruction of the administrative state, has spread his ideology by coaching right-wing nationalists worldwide. Hes been given shrift by nationalists in the U.S. and U.K. (obviously), Russia, Czechoslovakia, Poland, Italy, France, Sweden, Israel, Brazil, and hes expected to consult on 45s re-election bid (no surprise there).
Just take one look at Bannon: his crusty, greasy, scabby, moth-eaten, repulsive exterior dark is merely a reflection of the disturbed, dark undercurrents going on INSIDE the man. More than any other alt-right/neo-fascist, Bannon got the ball rolling for 45 and his team of far-right extremists. (They are anything but conservative.) Hes even acknowledged having a role in selecting 45s insane, ill-fitting and nihilistic cabinet appointees, stating that they were selected for a reason, and that is deconstruction.
