The real bullshit is calling scrawling your name on a bathroom stall "Vandalism". The term comes from the Vandal people sacking the city of Rome for two weeks straight, plundering everything down to gilded roof tiles of Roman temples.

I don't know quite where it started, but there's definitely the Christian and legal concept of sin/crime as a qualitative offense rather than a quantitative one. You are a murderer if you kill one, two, or five people. At some point you become a mass murderer, but that's the same whether you kill a thousand, or a hundred thousand. Likewise you're a vandal whether you appropriate a bathroom stall by writing your name on it or you destroy a river. You're polluting a river whether you chuck a bag of garbage in it or dumping industrial quantities of waste that kills dozens.
