A lot of them probably aren't interested because they prefer to think that there are no problems. Because being asleep is rather more comfortable. When you think there is a problem, and that big a problem, that can make you feel rather stressed, especially if you think you may not be able to do anything about it because you are just one of the little people. So, they ignore all and every proof no matter how convincing simply because they find that much more comfortable.

That is not to say you shouldn't keep trying. Every single person who gets red-pilled is a gain for your side, and some always will if you keep chipping on their defenses long enough.
