what threat does david make to mr. nake? do you think david threat to sue mr. nake is realistic? why or why why not?

After a classroom debate on whether the United States should have closed its borders in 1900, David Petrakis hires a lawyer and threatens to sue Mr. Neck and the school for civil rights violations. Mr. Neck is forced to behave for the rest of the year. I think it is realistic in the sense that Mr. Neck overstepped his bounds as a teacher. He walked the fine line between social studies issues and hate rhetoric. Yes, it's quite possible a student might want to sue.
