Great diatribe, except that the post does not address the reason "concernfags" take issue. Their issue is not that they don't understand, as you seem to suggest. Rather, if you read enough of their posts here and at several other locations and sources, you will see "frustration" throughout.
Many have been fighting this for a long time, longer than the months of this board.
Short answer, they want to finally see the bad guys get punished. It appears that McCain is going to be allowed, essentially, to get away with his corruption. He lived his life, did his crimes and now will be able "to die."
Imagine being one that he screwed…. yeah, go ahead and call one of those guys a "concernfag."
