Ok Turkanon, here's why I, personally, hate your country.
Besides the point that everything west of Hellespont should be given back to the Greeks.
The main reason is what modern Turkey is, simple as that. The Ottomans were actually pretty cool guys. Prior to the 20th century, they largely let the Greeks and Armenians and others be, live and let live. Enver Pasha was a faggot, but besides him, most of the Ottomans were ok.
They did some really cool shit, yes they conquered large parts of Europe, but they did it by being better than the defenders, and they lost eventually by losing their advantage and being outclassed, this shit happens. They contributed a great deal of art and architecture and science to the world, and they kept the middle east largely pacified for almost 4 centuries, which is an impressive feat.
The problem was what happened after WW1. Turkish republicanism and Turkish nationalism are fucking disgusting. Ataturk is literally on a par with Lenin and Napoleon in terms of absolute scum.
Since 1922, Turkey has gone from a relatively multicultural, art and science producing, tolerant place to a fucking cultural sewer. The process of Turkification was the biggest mistake that country has ever committed. They literally made the entire country a vile, shitty fucking bland as fuck Islamic banana republic, purely because they wanted social cohesion after they destroyed the Ottoman Empire, the only legitimately cool Islamic empire to have existed since the Abbasids. They also abolished the Ottoman caliphate, the only thing keeping Islam together, and stopping it from being the absolute retard mode ideology it is now.
Republican Turkey is an ignorant, regressive, revisionist, pseudo-fascist shithole. Given the heights the Ottoman Empire achieved, it is actually staggering how far Turkey has fallen in the last century, and how much disgusting shit they have perpetrated against people who were once their own citizens.
