Indeed! And while it's nice that the United Nations seems to understand this on some level, their own practices leave much to be desired. I communicate pretty much everyday with queer refugees at the U.N. refugee camp in Kakuma, Kenya. These refugees have fled to Kakuma because they have faced violence and terrible mistreatment at home in surrounding nations. At Kakuma, they are subject to constant hate speech and ensuing brutality, not just from fellow residents, but from U.N. staff.
So, people at the U.N. know on some level that hate speech leads to violence, but knowing isn't enough to stop the hate and violence.
This is something we queer people deal with everyday, in Africa and everywhere.
So thanks for writing about hate speech. Maybe one day, we humans will start learning for real.
