"Africa's HIV-infected children also ignored"
Why is it the world's problem?
12 million children orphaned and 2.5 million with AIDS isn't necessarily the world's problem, but it is something that people should know.
These children haven't done anything to deserve this life they have. It is very sad to see so many suffering. Some people care about that. I am sorry for you if you can't understand.
"Why is it the world's problem?"
Read the gospels. All of them. Or even just the first one. Or even just the red lettered words of Jesus. From "love your neighbor as yourself" to "whatever you did for one of the least of these brothers of mine, you did for me" to "it is easier for a camel to go through the eye of the needle than for a rich man to go to heaven" to "sell all your possessions and give to the poor" to "blessed are the merciful, for they will be shown mercy" to the words of James, the Lord's brother:
"Religion that God our Father accepts as pure and faultless is this: to look after orphans and widows in their distress and to keep oneself from being polluted by the world."
On my darkest days, I realize how marvelously blessed I am, living in abundance of food, medical care available for even my minor ills, peace and comfort envied by most of the world. It would not hurt even one of us to contribute toward helping those poor children. It is a real problem.
Perhaps you are not believers. But as Freepers, your callous attitude rips the heart out of conservatism.
