An old friend of mine was turned to the dark side of liberalism while studying to be an attorney at the University of Michigan in the 60's. He married the daughter of a man who owned a gas station. She worked as an operator for Bell Telephone back when my friend was getting turned. They have lived the good life since then. They live in a home on 3 acres in the "best" neighborhood. They are wealthy. They also own a home on a lake. They have all the notable cars and toys. They hang with all the "right" people in our town...college professors and administrators, Judges, doctors, and other lawyers. He has his own multi-attorney law firm.
He, at least, pretends sometime that he's not the far left proud liberal that we both know he is when our group of Coots meet for lunch each month. He brags he voted for W when I know he didn't. The wife not only is an avowed liberal, she is one to the point of my wanting to reach across the dinner table and slap her face at times, even though she is a lifelong friend. It is absolutely impossible to carry on a conversation with her that doesn't wind up being a lecture from her about how folks like me are knuckle draggers and folks like her are the salt of earth. I do admit to baiting her at times when I was younger. Now I just try and ignore her.
Example: When I retired, she said this to me: "Well, you have a substantial 401k, also a company pension and you collect SS. Haven't you considered not taking your SS so that SS would be more solvent and those less fortunate than you would be better off with that money?" To my chagrin, I was struck dumb by her comment and kept my mouth shut. On the way home I mentioned to my wife that I should have said to her, "Yes, I'll give the money back to SS when you turn your home on the lake over to a homeless family."
What I have found in our 60 year friendship is that any conversation that challenges either of their hypocrisy and self righteousness is not only an exercise in futility no matter the evidence, but makes for a sour stomach and an intense desire to beat my head against a wall. Sparring with liberals is an exercise in self flagellation and is futile.
