A hate crime is a criminal act that is motivated by bias against a race, religion, gender, sexual orientation, etc. In short, a hate crime is a traditional crime (such as assault, arson) with an added element of bias or hate. Many law enforcement agencies have special hate crime units, including the FBI and the NYPD.

Hateful and offensive speech is not a crime. The First Amendment protects hate speech unless it crosses the line to true threats, harassment, or incitement of imminent illegal activity. In a private, non-government setting, hate speech may be subject to limits and regulation by the private entity.
