Let's make this clear: responding to your teenage child's words with violence is NOT OKAY.

125. OP goes over the top, too, threatening taking away children for property destruction

Parental termination cases can be filed in certain cases of more extreme neglect or abuse, but not for a single case of destroying property. The OP, while making a fair point that this is not good parenting, goes well beyond the pale -- just like the behavior it criticizes -- and suggests that a person is not qualified to be a parent if they destroy property. While I suppose no parental termination action is expressly threatened, it is suggested, and that goes well beyond what the law allows in its own way.

Would be best just to urge reconsidering the behavior on an ethical basis and not suggest the very right to parent is undermined due to lack of "qualifications". Maybe if the behavior was a pattern repeated over a serious length of time the suggestion would be approaching the range of debate-ability.

In other words, there "is NO SCENARIO under which you are justified in threatening {the parents of a} child with {the} violence {of parental termination}, period" based on a single instance of property destruction.
