Why do people get so fired up when someone talks about helping people from other countries?

So many people snap that there are plenty of people and kids here in the U.S. that need help. We know that, but there are so many MORE kids and people who need help all over the world! We are the richest country in the world by far, so why is it such a big deal that some of us want to go overseas and help the people who have absolutely nothing? I know that there are people in the U.S. who have nothing, but they are far more likely to get help simply being here than people in Africa if caring people don't go there. It doesn't need to be an argument. Can't we just care about everyone? God calls us to go to every nation.

I believe that part of it comes from the quote thea."Charity starts at home." After that there is the giggle factor of America's attempt to save the world when it cannot even take care of it's own needy. So many complaints about poverty and failing education in the US and charitible dollars, foreign aid, and UN funds are streaming out to the world. How about Oprah's $40 million school for 150 students in South Africa, which was supposed to miraculously transform into a paradise after the evil white devils were removed from power. There are quite a few schools or districts that could use $40 million. I guess the American people that put her in the wealth aren't good enough for her help.
Reply:We try and do help every nation in need by answering God's call. How do we ask God to please have them stop kicking us in the rear, spiting in our face, and their leaders stealing our generosity while they are accepting our aid or screaming they are not receiving enough.
