What would questioning disguised pacifists accomplish anyway? The Gaza flotilla’s mission is a humanitarian mission first and foremost

Reading Christopher Hitchens’s article, titled “Some questions for the ‘activists’ aboard the Gaza flotilla”, in Tuesday’s edition of the National Post, almost got me to write a letter to Mr. Hitchens, the old fashioned way, to ask him the following question:
Assuming that the individuals aboard the Gaza flotilla are in fact aware of a Hamas, Assad and Iranian collaboration, what good can come out of questioning them?
If my understanding of the article is correct, then Mr. Hitchens makes the point that journalists should be more focused on finding out about the allegiances of the individuals onboard these flotillas.
Mr. Hitchens proposes a decent question since the answer may allow the Israeli government to gauge the intentions of those aboard the Gaza-bound flotilla.  
However, I personally think that Israeli security officials aren’t that lapsing that they don’t already know about the intentions of these activists. I wouldn’t be surprised if they planted a mole of some kind in each and every one of these expeditions.
Speculation aside, what if we indeed asked the ‘activists’ about their understanding of their backer’s agenda?
I only see three potential answers that may come out of such questioning:
First, the flotilla activists admit that they are aware of the Hamas, Assad and Iranian collaboration mentioned above.
Second, they deny any political motivation for their actions and claim that they are only doing this for humanitarian reasons. That, despite the fact that their supplies are ‘negligible’ as Christopher Hitchens puts it, they are still willing to ship whatever they can to the desperate peoples of Gaza, regardless of consequences.
Third, they deny political motivation by presenting a more pragmatic answer: That they have no choice but to cooperate with such regimes as Hamas, because of their influence in and control of the Gaza strip.  
Now let’s ask the corollary questions:
If these activists admit that they are aware of the extremist ideology that helps them deliver the minimal goods they’re carrying aboard the flotilla, would that mean the humanitarian aid, perhaps more substantial in bodies than anything, is not worth it?  What if these activists can save just one child with their supplies? Are they then to be reprimanded still for what they believe?
I say no one should give a damn about ideology when lives are at stake.
Assuming that these peaceniks are oblivious to the ideology supporting their efforts, well then we can’t blame them for being ignorant now can we. At least in such a case their intentions would be pure.
Finally, what if these activists have no choice but to cooperate with the before mentioned forces just to deliver even a minimal amount of aid to Gaza? Taking aid to Palestine the official way, through the Israeli border and ports, as we have seen before, did nothing to alleviate the suffering of the Palestinian people.
Also, the international community has largely abandoned Gaza and there’s little we can do to impeach Israel on its conduct.
So I think then the symbolism that Hamas is trying to promulgate with these boats can be safely ignored, regardless of Hamas’ warped ideology.
