I tend not to view people’s “feelings” as fact.
Even so, it is a fact for her motivation; to say otherwise is, bluntly, stupid and ignorant on your part. (Or do you wish to put forward an argument that not only should people be utterly rational/logical, but that they must be?)
Furthermore, is not this a curtailment of free speech? To call it an obstruction of justice to warn people of the consequences of their actions is to assert that learning the law is obstruction of justice.
