I certainly understand the temptation to relent; to watch as the "Forces of Darkness" seem
to prevail despite our best efforts to restore civility, tolerance and sanity to our government and to eventually just say: "To hell with it!" But, I believe---at least most of the time---that optimism is often a self-fulfilling prophesy and that a positive attitude is almost magnetic in that it attracts positive people with similar attitudes and that the whole is ALWAYS greater than the sum of its parts.
I am not a Pollyanna. I am a sober thinking person who has earned his share of scars, has buried his dead and, on occasion, has behaved in ways which still embarrass me. But, nothing I have experienced has caused me to doubt the wisdom of Dr. King: "The arc of the moral universe is long, but it bends toward justice". Eventually, right will prevail.
"Go at it boldly, and you'll find unexpected forces closing round you and coming to your aid"---Basil King.
