Not every factoid is going to work on every person. Learning about LRH's real history didn't do anything for me. A true believer Scientologist might just say, "That shows that Ron was just a man like any other, but he was at cause enough to rise above the bank."
I remember having a great "explanation" for any "outpoint" I came across. But everyone has something (or a bunch of things) that nags them in the back of their mind which they never speak about. They might think they're the only one who notices that the emperor has no clothes. It can be a big deal to find out that other people also see the same things they do.
My advice is to find out what the person thinks is wrong, or what they are upset about within the organization. That gives you an idea of what's important to them. And then you can go from there and start giving them some personalized guidance.
