3.5 million people were slaughtered by Turco-Islamism, including 353,000 Pontic Greeks.

Omissions

• The claim does not specify the historical period (roughly 1914–1923) during which these events occurred.
• The term 'Turco-Islamism' is a non-standard, ideologically charged framing; mainstream historiography attributes these deaths to the policies of the Ottoman Empire and Turkish nationalist forces rather than to an abstract ideological construct.
• The 3.5 million figure is a combined estimate covering Armenians, Greeks, and Assyrians — the claim does not disaggregate these groups beyond mentioning Pontic Greeks.
• The 353,000 Pontic Greek figure and the 3.5 million total are scholarly estimates, not precise census counts, and different historians propose varying ranges.
• Only secondary and advocacy sources could be located within the search constraints; no primary academic source was directly accessed.
