The Ottomans had a culture of plunder, looting, genocide, rape, abduction of greek babies which were made Genitsari, and desecration of religios sites and churches. They sacked villages and burned them to the ground, destroyed libraries with historicall hellenistic artefacts, and ethnically cleansed all of Asia Minor. They stole the Byzantine culture and made it their own since they had nothing themselves to offer.
All other empires, such as the Egyptian, Greek, Roman and english empires have offered the world knowledge, sciece, arts etc. What did the Ottomans offer to the world? Afterall they were mere nomads on horseback from Mongolia.
Even The EU is hesitant to allow Turkey to become a member, because what has Turkey offered to the world in the past and what will they offer in the future?
