What makes a crime a hate crime?
In general usage, a hate crime is a criminal act in which bias toward a protected characteristic is part of the motivation. The underlying offense still has to be established; a hateful belief or unpopular opinion, without a qualifying criminal act, is not by itself a hate crime.
Supporters of enhanced penalties argue that bias-motivated attacks can harm both the individual victim and the wider community associated with that characteristic. Critics question whether motivation should affect sentencing beyond the harm caused by the offense itself.
A distinction worth keeping
Hate-crime laws address criminal conduct and its motivation. They do not generally criminalize an opinion merely because it is offensive. Constitutional speech protections remain an important part of the legal discussion.
