If everything in the universe exists in a state of polarity then it is unlikely that your wish will come true, if only for that reason. It seems that longevity does not bestow enlightenment or wisdom upon every individual or institution, especially, if they are entrenched in their positions and have a vested interest for remaining there.

Like every process of evolution it takes lots of time to get it done. Keep your fingers crossed that whole planet will be enlightened in our life times.

It will never disappear. We are so hardwired to see padrons that there will be always some false positives going around.
We all have those, no matter how rational we are there are always some face value believes that we carry. It would be highly unpractical to investigate everything.
The important point is to be open to give a step back when some of those "truths" are questioned instead of reacting emotionally.
