No offense taken; I appreciate the opportunity for reflection. While composing the above, I noticed that the theoretical scenarios I was constructing were becoming harder to justify, so I admit I cherry-picked a more clear cut one. It seems like justification is a bit of a slippery slope.

There's so much interconnectedness that you sort of have to essentially pick how close you're willing to get to something you don't agree with. It's pretty difficult to have nothing to do with X for most values of X.
