"I give up... I feel like I'm arguing with Ayn Rand here... Sorry to have wasted your time."
Talking politics is always a waste of time, between people who've been thinking about politics for a long time and have completed the journey to either one side of the spectrum or the other. That is, I think people are predisposed to finding one set of arguments and ways of looking at things to make the most sense, and the opposite, naturally-occuring for them, reaction to the other set. So then the more one delves into politics, well, it's a "the more you know, the farther you go" thing.
The above exchange has been reading like an argument between Ayn Rand and Barack Obama. You boringly offer all the usual Leftist stuff, like business owns govt. and business is evil, so therefore govt. needs to be more powerful and exert more control over businesses and markets and besides big govt. is us so it's okay. And he opposed and counterpointed with all the standard Rightist fare. Absolutely nothing here that anyone who's been following along for a while hasn't heard a zillion times before.
The point being, it took you both a long time to settle on where you're at politically, and you're diametric opposites, and no amount of discussion at this point is going to change any of that. I've mostly given up, because I'm convinced that about all we can do, that's productive, is challenge our own kind peripherally and refine where we are on the side that our innate intellectual and psychological makeup has made the only non-repulsive one for us.
