Those should be removed too. People have no right to criticize people like Erdogan and Kim Jong Un. They are working their butts off to try to make their nation great, and their worthless populations aren't helping things by voicing criticisms.
Ok I see your point. Perhaps the line should be at calling for violence against an ethnicity or innocent individual.
If for example someone on the street calling to stab people of certain etnicity and show a diagram of where to stab to make the most damage, will be arrested in most countries. I don't see why Facebook should be any different...
