See, i agree with all of that,but where is the line of "racist" and "charity".
I think there's a line between racism-racism, which sounds like what you've been seeing on blogs maybe (people thinking these guys are just thinking "Hey, lets show these dumb spades how to run a country!") and misguided, patronizing racism ("Hey, lets help these poor, misguided, child-like negros and end their plight!").
These guys are the latter.
I mean, who doesn't want to be a hero? But, they're just clever and just aware enough to realize that they don't have the clout to do it, so they turn to well meaning but largely ill-informed 18-25 year olds to help fund their adventures off helping the noble savages of Africa.
