He is the hero of the Arab world who eliminated the Ottoman subjugation. It is time that the supply of Ummah brotherhood kool aid is ended.
Turks take pride in the empire they built; it is natural. However, the thought that this empire was some custodian of Islam is nothing but a childish fantasy. Having pride in your past glory is OK but selling it to others in the name of religion is self-righteousness.
It's like the British colonialists who sincerely believed that their Empire brought civilisation to the oppressed people. These days, America thinks it is the flag-bearer of rightness, democracy, freedom and civilisation.
Every empire in history only served itself. That is human nature.
