I'm not saying I wouldn't welcome him as a brother in Christ if he did have a Damascus Road experience, just pointing out the magnitude of the necessary change motivation.
Oh Hell, it would take a whole-head transplant to turn angry Bob around.
I suppose he could run into one of Skippy's pals and get the first half of the procedure done, but I dunno who'd be in charge of putting a new head up there once the old one's taken off.
My theory, based upon decades of first-hand and up-close observation of the hippie older brothers and sisters and their friends, is that Democrats, liberals, primitives, and hippies are so angry, so resentful, so bitter, so hate-filled, because they've rejected those forces that created them--such as family values, religion, social outlooks, personal attitudes--and in doing so, they've rejected themselves themselves.
So no wonder they're all pissed off; they hate even themselves.
The only remedy I've ever seen--and I'm not a young man--is a return to those basic values which initially molded one, accepting oneself again.
In angry Bob's case, he's a lapsed Catholic. I'd suggest lapsed Protestants and secular Jews try a remedy more in keeping with their own upbringings, but in the case of lapsed Catholics, it's best that one go to a priest, admit that one's been a rectal aperture, and resolve to make amends for all of one's past arrogance, conceit, egoism, pride, and other sins.....and then go out and actually make those amends.
Such would change angry Bob in a hurry, but I doubt he's got the moral fortitude to face himself, to see how he's for most of his life been an ass.
