"It is disappointing to see that even after a decade of building awareness by the Hindu-American community, textbooks especially by Houghton Mifflin Harcourt (HMH), McGraw-Hill, Discovery and National Geographic continue to use orientalist narratives to portray Indian civilisation," said Shantharam Nekkar, director of Hindu Education Foundation USA (HEF).
Mr Nekkar's remarks came at a public hearing conducted by the California Department of Education (CDE) at Sacramento on Thursday.
For the past several years, the Indian-American community has been battling to remove several inaccuracies and myths about Hinduism from the textbooks. The State of California mandates that the textbooks to be based on the framework laid down by the Department of Education. The framework was revised last year amidst many controversies, including attempts by a few academics and groups to replace 'India' with 'South Asia'.
Over the past two years, the Department has made several updates to the framework based on inputs by scholars, students and the community members, mentioning Hindu concepts like Yoga and Dharma, Sages Vyasa and Valmiki and Indian achievements in science and technology.
"Some publishers continue to single out and denigrate Hinduism while ignoring new additions to the framework that can help present Indian civilisation on par with other civilisations and cultures," said Sharat Joshi, a parent from San Jose.
"Negative portrayal of Hinduism has led to several instances of bullying of Hindu children in classrooms," he added.
The Department of Education will send its recommendations to the State Board of Education (SBE) later this year for its approval. The textbooks recommended by the board are expected to be adopted by schools starting early next year.
