People dislike those who refuse to admit any wrongdoing whatsoever.
So Turks who deny Armenian genocide, label all Kurds terrorists and ignore their own government sanctioned atrocities, etc etc... those are the types people dislike.
Just like people dislike Israelis that think they are doing god’s work on the West Bank with the settlements.
Or Americans who think Vietnam, or more recently Iraq, were justified invasions.
Or Canadians who think residential schools for First Nations were not a terrible atrocity.
etc.
Of course, the absurd nationalists running rampant in the world today, see nothing wrong with any of their own nations actions regardless of how evil, and see any criticism as a direct attack on their nation.
