You live in a country with a wildly corrupt government that repeatedly lies to you and regularly unburdens you of your basic human rights. Then one day, officials from this government force you and everyone you know at gunpoint to submit to a series of "tests." You notice that, all of a sudden, many of the most social and/or eldest (therefore vocal, therefore most likely to be community leaders/government dissenters) among you go missing and later mysteriously die. For good measure, a number of kids randomly disappear and die as well. The ones that survive tell horrible stories about the dismal conditions in which they were held, where they were injected with any number of things and only a few days later, became sick . The government (the same government that lies to you and considers you subhuman) tells you that the cultural practices that have been with your group for a thousand years are all of a sudden, just now, for reasons they don't have time to explain, causing you to get sick and die, and it just happens to selectively be wiping out the kids and the community leaders.
If it were the US doing this, I conjecture that at the very least, this comment thread would have a radically different tone. Less "these guys are idiots," and more "these guys are heroes." What we're witnessing in Liberia is a tragic consequence of a corrupt power structure attempting, maybe for the first time, to legitimately help people that it has previously subjugated. The whole thing smacks of people acting in their and their community's best interests based on many many previous data points telling them government=bad, therefore avoid government. Unfortunately, it takes time to build a relationship of trust between a government and its citizens, and in the face of the calamity that Liberia is confronting, neither the government nor its citizens have any time to spare.
