sarah, some of what you perceive to be harshness and a shock to your system (I know what you're talking about -- I had to adjust to that reality, too) actually hits right to the core of a matter and to behavior and mindsets of a poster that should be nipped in the bud, so to speak, if they want sound legal advice. If done in a more coaxing sort of manner, more like a mental health counselor, it would take pages and pages of dialog to pull things out of a poster. Experienced seniors can already get to the heart of things, having seen it thousands of times by now. It may sting and feel like it sucks, but having a dialog go on for PAGES won't help anyone and won't be of use to others searching for help on a keyword to have to wade through all that.
Seniors aren't infallible. If an assumption is made by one and a further response indicates they were off base, you'll always see a recanting of a previous response and harshness.
P.S. Stepfamilies getting along would be the best for everyone, but when things go sour, like with anything, it's back to the letter of the law and pulling out the "contract" and the stepparents simply are not on the contract. I'm both a CP and stepmom, BTW.
