How is ensuring his message is heard celebrating suicide? Are you saying it’s better if we ignore this message that he felt so strongly about as to literally end his life? What in God’s name are you trying to say? He ended his life in an act of protest against the genocide and ethnic cleansing of Palestine. The idea that we should not respond to that is genuinely offensive. Your description of him as scared and lonely without even knowing him is also genuinely offensive.
I have lost friends to suicide. I myself have been suicidal. I don’t know anyone who ended their lives by committing acts of self immolation in front of a genocidal colonial nation’s consulate.
What about the Vietnamese monks who self immolated in protest of the persecution of buddhists in South Vietnam? Thích Quảng Đức was one of them. His action is regarded as heroic.It would be offensive to suggest that his message in death not be remembered. It would also be offensive to suggest that he killed himself for some other reason. As though there’s no conceivable motivation someone could have for taking their own life other than mental health problems.
