I think you just like to pretend this isn't true. The ones that just send food usually aren't Christian, and I happen to respect those ones.
After the tsunami struck I had some great examples of Churches that were rallying missionaries because 'the door was open' for conversion, they were going to do aid and relief, but the major motivator was that they could get into that region, an area Christians had been restricted from, and preach. But alas too much time has passed for me to provide you with those links.
So, no, I'm not just making empty claims. TBN should proof enough that many of these organizations are more interested in promoting themselves and the word of God than doing any actual good.
Let me ask a question, and maybe this will open your eyes. These people are starving to death and illiterate...what good is a new/used bible going do for?
