Adding religion to the school curriculum would mean perpetrating some religiously biased ideas.

It will be demeaning for people who don't belong to religious groups.

They'll feel excluded, and here the discussion is about children, so binding them with any kind of religious thought will not do any justice to them.

It is absolutely a stupid way of eradicating conflicts as it is going to give rise to more conflicts.

Religious education in the school curriculum will disregard the cultural diversity and the personal beliefs of any students.

Furthermore, it will make them feel like "other" who is inferior to religious groups in society.
