Try to be more careful about the term "FUD". I know it isn't written anywhere that this is the case, but in reality, "FUD" implies a bad-faith effort to convince people to avoid something; it means the person spreading the message doesn't care if it's true or not.
There is a big difference between that kind of "FUD" and simply being incorrect or under-informed about things, even if you think people should have an obligation to be better informed before relating their opinions.
