But didn't you see that movie about the guy with the hotel?
I think you are referring to Hotel Rwanda. No, I didn't. I am hopeful that this is a joke and not an attempt to disprove my point or a demonstration of your range of knowledge on the subject.
That was the Rwandan genocide. It's the same incident.
BTW, "Beyond the Gates" (aka "Shooting Dogs") is another film about the Rwandan Genocide, but much more violent than "Hotel Rwanda". It also touches on a bit more of the white/black racism as well.
that depends on what your interpretation of 'common' is. my measuring stick is europe. it's common there. 3 times in one century is common.
