Why is "Gaza Thesis" trending?

Wikipedia Overview

The Ghaza or Ghazi thesis is a since disputed historical paradigm first formulated by Paul Wittek which has been used to interpret the nature of the Ottoman Empire during the earliest period of its history, the fourteenth century, and its subsequent history. The thesis addresses the question of how the Ottomans were able to expand from a small principality on the frontier of the Byzantine Empire into a centralized, intercontinental empire. According to the Ghaza thesis, the Ottomans accomplished this by attracting recruits to fight for them in the name of Jihad against the non-believers. Such a warrior was known in Ottoman Turkish as a ghazi, and thus this thesis sees the early Ottoman state as a "Ghazi State," defined by an ideology of holy war. The Ghaza thesis dominated early Ottoman historiography throughout much of the twentieth century before coming under increasing criticism beginning in the 1980s. Historians now generally reject the Ghaza thesis, and consequently the idea that Ottoman expansion was primarily fueled by holy war, but disagree about what hypothesis to replace it with.
