When you take the 'red pill', it is followed by a period that some people call the black pill. Where the shock of having your world turned upside down, puts you in a depressive state as you start to question your own existence up to that point and all the choices you made or did not make based on that false world view. It is really easy to become jaded and nihilistic during that time, and honestly with some people it never fully goes away.

I think this posts illustrates this fact, that for many, it is just easier to keep on with the lies.
