Yichusdik, #1 is irrelevant to the actual discussion. Credibility is an issue only when you need to take his word for it.
#2, Second, he made the false, absurd, and infuriating assertion that almost every divorce is criminal.
I don’t know how you know it’s false and absurd. If both parties would work hard, it’s very possible (although I honestly don’t know for sure) that the majority could be salvaged. It’s infuriating to divorced people because it seems to implicate them, but, a) they may be in the 5% b) it might be that they were not to blame, only the other spouse c) the point isn’t supposed to be laying blame, but motivating both parties to do their best to work things out for the kids’ benefit.
#3, I disagree, it could just be carelessness, and spouses/parents need to know how damaging it is.
