A deep hatred for a community to the point where you take violent action (in this case the murder, brought about by clearly a mental illness that latched itself to hate for the lgbtq community).
So much of this imo has been perpetuated by social media, online presence, and lack of community and connection for so may, which can lead to depression, anger, and other mental health issues. It’s sad and we need more help and resources for people and less hate and fear-mongering
