I've talked to plenty of perfectly nice individuals on Omegle in text mode. But it's not like people want to talk about deep topics right of the bat or at all. Perverts aren't to blame for that not happening. Given random people most won't even know as much as you do about their country's situation and whatnot. A 1 to 1 chat with a stranger is a really bad format for that kind of conversations too.

What you can do is, say, talk to a Syrian refugee about cats or pizza.
