I've found that by not engaging, I don't have to ignore by key; I even see rushmc's posts when they show up. But I haven't answered one (or generally read one) in a long, long, time. Just not worth my time.
But Turtle, you doubt from the right, from a place where (most likely, based on what I know about where you at least used to live) nearly everyone thinks that liberals are wrong unless proven right, and conservatives are right unless proven wrong. Lots of others here on DZ.com doubt from the left, as I generally do. One of my brothers is more liberal than I am, the other more conservative - but only the more conservative one could really be considered middle of the road, and maybe that's only because none of the three of us is as liberal as our parents.
Some folks just double down in all cases, like rushmc and that guy who posts incredibly long unreadable diatribes on the left. What looks like the middle of the road can be shaped by where all the people, or at least all the people you care about, are.
Kind of like how used to be done about minorities by just about any majority: "I don't like grinches, but that Natter is a good guy."
