Why should you be required to study religion at school?

The teaching of religion is not the role of schools as there are inherent biases. Religion should be taught in religious based classes outside of schools or in the religious community.

A lot of work has gone into the fabrication of religious texts and discussion over the years. It is worthwhile to study these to see how mankind has attempted to define its role in the Universe. However the merits of taking one text (Qur'an, Bible, Bhagavadgita, Tibetan Book of the Dead etc.) as the "best" are not evident. Religion taught in schools tends to be centered on the faith of the local population and thus somewhat biased.

In addition, the teaching of religion in school would require a depth of understanding of the subject not found in the average highschool teacher. Just attending a local fauth based group on Sundays is not enough. The teacher would have had to be a theologic scholar at a Doctorate level comfortable with balancing the teachings of dozens of faiths (past and present) without denigrating one and praising another (Just the facts)

Teaching methods at schools are aimed at being able to have right answers parroted back in exams. In religions there are no right answers only opinions. Could exams be developed to allow all the personal understanding to be grades, and if all answers are equally correct would not the only exam result be 100% correct every time.
