Actually in the Bible there are were places and situations under which Jesus did not bother trying to preach the Gospel, and instructed his disciples not to as well.
(example; Jesus telling his disciples to shake the dust off their sandels and NOT preach in some towns)
We can debate whether or not this is one such situation...but the Bible does not teach that preaching the Gospel is ALWAYS right or inspired regardless of the circumstances.
You're correct. However, you must at least admit that much of what was done in His name throughout history has been TERRIBLY wrong. The Inquisition--with forced conversion of the Jews, the "rape" of the Americas by the Catholic Spanish, and many other instances where "light" was supposed be brought to the savages come to mind.
I absolutely applaud the attempts to bring sustenance--both temporal and spiritual--to this unfortunate people.
Just make sure it is done with an open hand, not a closed fist.
