Good advice. I found over time rather than trying to drop the giant red pills and arguing with family, just point out the inconsistencies and the facts in passing or in regular conversation. As time passes, they will see that what you are saying is right. This is how I did it, my family thought some of my theories were bat shit crazy. These days more often than not I hear things like, "you were right about that". When that happens never say I told you so, use it as an opportunity to bring in another point that will open their eyes.

You want to lead them to truth. Not prove that you are right.
