Admitting theres a problem.means admitting they or their lived ones did something dodgy too.
I think this whenever somebody on AIBU posts along the lines that she doesn't want to visit her mother and step-dad with her own children because of the latter's history of SA of her as a child. And then a brother chips in with, "Oh, but he's alright now. You're making a fuss about nothing and breaking up the family."
Because the step-dad's transgressions didn't do that...
