When I first came across the "WalkAway" thing, I guess what resonated with me is that I am ready to walk away from most expressions of extremism.

Perhaps those who occupy the polar extremes of opinion serve a purpose... they become our "canaries in a coalmine" that stirs people from complacency, and it's through their shrill voices and flaming self-destruction (currently personified by the "Liberal Left) that we come out of our comfortable stupors... and (as you suggest) become individuals again.
