Looks like a straight line to me. OK, how about this one. Achmed the corner grocery owner sells part of the store to his nephew Amir. Amir is a member of Hamas and his share ends up funding terrorism. You find this out. Achmed is no terrorist, but he can't or won't sever ties with Amir, even though part of their profits goes to Hamas. Do you still shop the corner grocery?
1) Me
2) Amir
3) Hamas
That seems pretty simple. Much simpler than Pampered Chef to Planned Parenthood.
Maybe you meant something like,
1) Me
2) Achmed
3) Achmed's Mosque
4) Mullah Amir
5) Center for Muslim Relations
6) Hamas
That would be more in line, and I would not have a problem buying canned peached from Achmed. He is only responsible for giving to his Mosque, and I am only responsible for giving to Achmed. If Achmed was sending money directly to Hamas, like Amir is in your example, then sure I have a responsibility in that step.
