You make claims. Release the books, and people can then verify what you say. If you do not release the books, it is only natural for many people to suspect something wrong.
That's exactly how it works. I suspect _you_ of wrong doing in a non-profit. I ask you do release the books, and if this is not done, I take that as proof of wrong doing. If the books are hidden and cannot be published, no one has any business giving you a dime.
And you are still not addressing the question here, which only compounds the suspicions.
I think you steal money from local orphanages and stomp kittens in your free time. Release your bank account and provide bodycam footage or you will confirm your guilt.
