I guarantee you there are Municipal and State Codes on what is permissible and what is standard street markings under current LAW. I guarantee there is no exception for RACIST Political Statements. Why hasn’t someone SUED??
The terms of the Law are irrelevant if those charged with its enforcement don’t enforce it or do promote contravention of it. In New York and Chicago and the Democrat cities and states the Law is a tool of the ruling class to be used as the rulers see fit.
AND ... the mayor of your town publicly started he’s painting the sign to p*ss you off!!!! is the mayor really allowed to decide where to paint a sign because he does not like you?
I’d be suing the city for ruining my property values.
