It causes division within society  Religious symbols, such as the veil divide society. When some Muslim women wear the veil, it creates pressure on others to do so as well. Pressure comes from wanting to fit in, and pressure from other people in the community seeing those who don’t wear the veil as being somehow less religious.  Allowing it in schools makes it more visible to non-Muslims, making them more likely to perceive it as a core part of the faith. It then gives the impression to outsiders that Islam is more extreme than it really is.
