Ya' know guys, I'm reminded of an old saying I picked up down in the Ozarks of my youth,
Arguing with some people is like wrestling with a pig in mud. After a while you realize that while you are getting dirty, the pig is actually enjoying it just for the joy of being in the mud. Sometimes all you can do is ignore the pig, step back, hose yourself off and let her wallow around, and after a bit she'll lay back down in the mud and sleep.
