'Isolationist' and 'anti-humanitarian' are not the same thing.

I see nothing in the parent's comment that insinuates this. What specifically are you referring to?

Whenever syria comes out, the propagandists come out. These people try to label people in order to marginalize their views.

You can spot them easily because they use labels like "trolls", "conspiracist", "tin foil hat", etc to label their enemies.
