Given the context of what community this is on, I kinda think it speaks to the right to self defense and the right to exist in a social climate where rabid, violent, right wing extremists want to eliminate trans people in every way possible.

And, just to throw this out there, it is not morally wrong to defend yourself against lethal threat or threat of significant bodily harm. It is also legal in every state in the US (check state and local laws though, as there are nuances).
