Six victims of the seventh victim.
I may take some flack for this, and I'm not excusing the inexccusable act of invading a school and shooting kids and staff, but I see it this way.
The seventh victim, a victim of trans-ideology, was shot because instead of getting her the psychiatric help she desperately needed, her parents, her culture and peers, her teachers/ministers/any adult in a position of trust failed to do anything but acquiesce to or help promote the delusion that she could be a different sex, that somehow that was the epitome of her woes, and do so to the point that her mental illness was nurtured to homicidal mania.
All of this could have been prevented by appropriate treatment of her fundamental psychological problems, instead of this incessant howling that biological impossibilities will make her world better, or that she is a victim of anyone but those who feed the delusions.
