Smudging doesn't belong in schools. Kids should not be taught that spirits and energies exist, or that smudging can improve your fortunes, or that people require spiritual cleansing. It's false and confusing to them. Public schools should not involve students in religious rituals, Indian or otherwise. You can teach kids about traditional beliefs and rituals without perpetuating those beliefs or endorsing them as valid. Kids must be taught to think critically and question all beliefs.
