They're not typical in Rwanda, for that matter. I'm visiting friends there for the second half of March, and one of the first things you're told by online guides, etc. is "don't ask people to talk about the genocide, or what ethnic group they are from". There was a horrific series of events with long-term repercussions and damage, no one wants to see anything like that again, and no one wants to discuss such things in idle chitchat with tourists.
