For anyone who brings up turkish diaspora.
Only 50% of Turks in Germany hold turkish citizenship. Of those only 40% vote. This means only 20% of Turks in Germany voted. Younger Turks that are born here are least likely to still have turkish citizenship. Erdogan wins by 67% in Germany. 67% of 20% is 13.5%. You are blaming all Turks in Germany for what 13.5% did, most of them are boomers which makes it more impressive that Erdogan only received 49% in Berlin.
