I’ll assume that you are American, so you obviously don’t understand how tone deaf that suggestion is to the current thread. Imagine someone commenting on horrible Auschwitz’s is after they visit and someone commenting “you should visit the Reichstag building to understand what lead to it all”, or a thread about 9/11 and someone suggest visiting a museum about the conflict in the Middle East to learn what lead to the events.

Obviously we are talking about completely different types of events and magnitudes of death and destruction, and the very notion that you should try to find justification for murder by events you can correlate to people who share ethnicity or nationality with the victims is just a cruel insult to anyone with a hint of human decency.
