Question

Interactional vandalism can be defined as a situation in which a subordinate person breaks the tacit rules of interaction that are valued by the more powerful person.

Answer 1

That statement is true.
Vandalism basically a form of violation that is conducted outside a generally accepted ruled/standards among specific social groups.
An action that could be considered as a vandalism in a certain social group may not be considered as such in another social group. (for example, it is considered legal to create a street painting in some part of Rio de Janeiro)
