I was kind of into it at first, after I watched the video. Then the next morning, I read a few articles about it to get to know it better, and I've decided not to take part in anything. I might do the posters if somebody makes/buys any, but that's because I love hooliganism late at night on the campus.
A few points to consider: The Invisible Children don't claim to be an aid organization, apparently. They've said that their whole mission is to make people aware and to start a "movement," which they have. The fact that 65% or whatever goes to their film making is quite justified. It also goes to transportation costs, which are costly of course. Flying hundreds of people around for filming and for awareness tours or whatever they do is expensive.
Now, I try to be an activist without doing it for moral fame. I feel like most of the "omgggg stop Kony 2012! He's so bad!" posting on Facebook is completely false. Just about all of those people are totally misinformed. I was for a few hours until I woke up the next morning and did some research. Now, I'm not going to take part in the sensationalism surrounding the issue. I'd love to see good things happen regarding the issue, but encouraging people to misguidedly dump money into things is not something I'll participate in.
On another hand, I'll agree that this guy has done some very, very nasty stuff and that he deserves to be reprimanded for what he's done. What we should do, is along with petitioning government people, we should petition Invisible Children to donate more money to the cause, since.. You know.. Their film has spread like a fire during a drought.
