Bringing attention to world events is not a problem but that is not the place for it. Schools want to be as partisan as possible and allowing kids to wear symbols of different ethnic and cultural backgrounds can make the look partial. Another reason is that these symbols have different meanings to different people. I love the eureka flag as a symbol of Victorians rising up against against injustice, unfortunately in the public eye this symbol has become synonymous with racism and hatred. This double/multiple definition means that school can’t look impartial if there are students displaying the symbol.
