Is the world selective in its outrage?

Two weeks ago in a single Assad airstrike on a marketplace in Douma, 80+ civilians were killed and 500+ were injured. Did Facebook ask anyone to change their Facebook profiles then?
Two years ago, in a single chemical weapons attack, nearly 1700 civilians - including hundreds of children - were gassed to death. Did Youtube change its logo in solidarity with them?
This is a serious point. This isn't just more moralizing. Doesn't anyone see a connection between how the Syrian people feel so absolutely forsaken, and the fact that IS can operate there?
The fact that the world says that "all human lives are equal", but it treats deaths in a European capital as far more worthy of solidarity than in a Middle Eastern capital, is a core ISIS recruitment point

And I am guilty of not posting what happened in Beirut and Baghdad here too
