It would feel nice to say this to DSS, wouldn't it? In MA, though, such an "aggressive attitude" could be noted by DSS. Then, when that "anonymous tip" came in on the child abuse hotline, they would most likely get an order from a judge to interview your children outside your presence.
The end of the process could easily be that they would try to cut a deal with your wife to leave the children in her custody ONLY IF you left the home, and began your anger management counseling. Laugh if you want--but I've read worse about that state.
You can refuse them politely, but then you'd better get a lawyer.
What would John Adams think?
