Distinguishing a hate crime requires reading the mind of the accused, a dubious prospect at best and perhaps not something that should be considered when deciding on punishments. In short, hate crime legislation
criminalizes thought (wikipedia.org) and denies
equal protection (wikipedia.org). In addition, hate crime prosecutions seek to punish an individual for
motive (wikipedia.org) rather than
intent (wikipedia.org). For example, the difference between first or second degree murder is intent, not motive.
