Basically anything that I could use to convince the wife that I was leaving in order to take the moral high ground. Obviously there's no shortage of issues with the cult that fall into that category, but since they're not new, it's difficult to take a stand on something thats been going on for decades.
A perfect example would be if they made blood transfusions a conscience matter. enforced tithing would do it, as well as a few other things. In lieu of that, I'll just continue to point out their lies as they come until they've added up enough that I can sell my leaving over that without setting off apostate alarm bells.
