I don't believe there are "too many" conspiracy sites in the list, maybe 10% and are there for informational purposes.
I understand where you are coming from. My only reason for suggesting that you exclude those sites, at least in the beginning, is because for many people, when they run into conspiracy stuff, they stop cold and go on to something else. There are serious problems and we don't need to turn off anyone. Later on, after they understand that there is a real problem, even if they ignore the conspiracy stuff, they won't unlearn what you have already enlightened them on. Just a thought...
