In a D/A letter I wrote several years ago, I used bullet points such as you mentioned in the post script.
I would not use that approach today, knowing what I know now. None of those things made me leave. They served as supporting evidence to myself for leaving. Real world human factors led to my decision to leave, and this is why 99% of JWs that leave, do.
A two class system, (us vs. them); misapplied or bad logic on every level; dishonesty; lack of love; a lack of integrity; etc., are the things that wake someone up eventually, when a certain personal threshold of tolerance for such things is exceeded. This cannot be forced, although these things can be highlighted in certain situations.
The best thing to do is discuss these types of concerns on forums like this one, and let folks come here on their own volition. This is the real difference maker in the information age in which we live today.
