To me, politically encamped means that you have decided upon a viewpoint without much thought. You sway one way because it's the position of your "camp" or tribe. And because of that you won't change your mind.

"pictures of dead kids wouldn't change their minds" does not necessarily fit the definition of political encampment. If they won't change their mind because it would go against their party's line then they are being political. If they won't change their mind because they believe their stance is correct (based on logic, facts, morality, etc) and/or the other alternatives are wrong (based on logic, facts, morality, etc) then that is not political.

I guess your saw encampment in the GP's comment? I didn't.
