Two presidential candidates, Cornel West and Jill Stein paid tribute to the act, and not just the young man. Not sure that this is a good idea.
Beyond Buddhist monks during the Vietnam War self-immolating, I also think of a Catholic Worker in the mid-60s, Roger LaPorte, who did the same. He was a troubled young man, and I have read that Aaron Bushnell grew up in a cult, and thus had troubles.
This is the censored video, but still a tough watch.
