What is the test for an equal protection claim under disparate treatment theory?

Plaintiff complains he was treated differently from American Indian religious adherents who had access to an outdoor worship area with a fire pit. To state an equal protection claim under disparate treatment theory, Plaintiff must allege that: (1) he is a member of an identifiable class; (2) he was intentionally treated differently from others similarly situated; and (3) there is no rational basis for the difference in treatment.
