a Turk said Iranians are looked down upon in Turkey like the Kurds, Afghans, and Arabs. Is this true or an exaggeration?

The Turk made a biased and unfair remark (1) historical Safavid Persia was the only Asian power to challenge and defeat turkey (2) turkey could never overrun Persia even under the weak Qajars (3) turkey was a chattel of the west out of fear of Russia (4) as early as 1878 turkey was saved from total defeat by Russia by Britain and turkey lost all wars against Russia except one (5) it remained a western chattel as late as 2009 and along with NATO s and USA tried to destroy Syria where NATO USA and turkey miserably failed
