Personally, I frame the event differently. I think it is necessary to remember and demand remembrance of trans* victims of hate crimes precisely because our murders, suicides, abuse and harassment go without notice or concern most days. If we don't make our reality of violence known, we can't work to change things.
Every TDOR event is a little different, but the event I am helping to plan on my campus is focusing on not only hate crime victims and systemic violence but also self-harm and suicide. In response, we are speaking of the resilience of trans* people who continue to fight for the right to survive, as well as the need to change things. We are also plugging the trans* support group on campus for trans* people who may be struggling with self-harm and thoughts of suicide. The event is also largely trans-led, which I think is absolutely necessary.
I think these events in general, however, would do better to be mindful of triggering content. If, for example, the event includes graphic descriptions of hate crimes, a trigger warning needs to be publicized. I think it's better to avoid those descriptions, though, because they can keep trans* people away from our own event.
