This stuff is like living in the Matrix. Even if we are 100% right there is 0% chance most people are going to "get on board" with it. IMHO instead the best we can do is subtle red pills over a long period of time.
Ive tried this before with other things, doing a "big reveal" to a close friend. It never went well no matter how much evidence I showed. You simply cant dump a huge amount of research onto someone quickly and expect they are going to get on board right then and there.
my 2 cents
Have them listen to Fall Of Cabal 10 part series by Janet Ossebard. If you haven't heard it, you should. Peace
She gets a lot right - but I believe some of her stuff may be less than accurate. Who can really say though?
I don't recommend this book. Look her up on Duck Duck Go
