Have you noticed that flags share the same symbols? Flags share geometric shapes: stripes, squares, rectangles, lozenges, circles, and stars.
They share figures, share icons, share colors and they're different flags, from different cultures, ideologies, and religions but they all have the same graphic elements.
Flags are different but they are essentially the same. There’s no prejudice, no discrimination and no barriers in this shapes. So why they still represent division? If you also believe that mixing is possible, please share.
