Before beginning today’s note, an acknowledgement of the recent tragedy in Toronto. Last Monday, 10 people were killed, and more than a dozen were injured, when a man drove a van into pedestrians. While the investigation into what caused him to allegedly commit this crime is still ongoing, he appears to have been motivated by hatred against women. I have written previously about the public health consequences of hate; sadly, there has been ample cause to revisit these thoughts in recent years, from the mass shootings we have regularly seen, to bombings like last Sunday’s attack in Kabul, to the hate that has infused much of our political discourse, both in the US and abroad. In this context, it is all the more important that we continue working to reduce hate and promote the values of empathy and community that are the basis for a healthy world.
