But my comment still stands, if our/your/whatever elected leaders are just people like us. Why treat them differently or expect facebook to treat them differently?
Your reason of him being elected doesn't make any sense to me. Saying it's the president makes even less sense. What about mayors, governors in the US? Do they get the same leniency as you give to president?
Your reason: "He's a president" isn't sufficient.
Societies work according to the rule of law. If the law doesn't make an exception if a customer to your business is a world leader, then why should you automatically assume businesses should make an exception for a president, or whatever world leader?
If your position is that businesses should make exceptions for your president then convince your congress to make this into a law. Currently this isn't a law in your country, let alone in mine.
Bolsanaro for example, says false things - would you know if you weren't brazillian?
How would FB achieve fairness in its policy if it put a flag on Trump and didn't on Bolsanaro, or other even worse world leaders?
What about some Random leader of a tiny nation somewhere who believes in witchcraft?
There are calls being made here which seem easy to Americans, but the processes behind it cannot be reapplied at scale.
How do Social Media firms handle that? How does anyone morally balance that out?
