When you mention a government/justice system, you must recall that those constructs have been approved and kept in place by the society that utilizes them. Thus the decisions made by these system are also made by society at large. Therefore, the society itself determines what constitutes a danger. For instance, you use the phrase "their society." Yet, if you were brought before the society's justice system that would imply that you occupy the same space as or are adjacent to an element of that society. And, since you use the term "their," it is clear that you consider yourself to be seperate to that society. Thus, you can't effectively contribute to the stability that society seeks to maintain. As such, it seems as though it would be completely reasonable to view you and those like you as a danger.
