Let's say you have a neighbor -- neighbor A -- who posts campaign signs for candidates you would not vote for on a dare.
And then you have another neighbor -- neighbor B -- who posts signs for politicians you support.
Well, the zealots would have you believe that there's no question you would prefer to have contact with neighbor B. But sometimes it tuns out that you actually like neighbor A better, depite your electoral differences.
Those who use politics as a litmus test for all human interaction wouldn't get that. But then, there's a lot they don't understand.
