3 Brothers Quarrel

............................................."Quarrel at Venta Nueva" by New Zealand artist Linda James, based on a work by Goya. (Source: artists.co.nz)

What is it with these 3 Middle Eastern religions that have taken over the world and just keep fighting each other? They are like 3 brothers from the same parents, grown up in the same house, living the same lives, but thinking they are so different. The world has tired of their petty quarrels.
