I did not say that Bushnell is cis man. The acebush1 reddit account identified as a cis man in 4 comments and the document mentions this. I said that we do not know. You are presenting a binary, that Bushnell must either be a cis man or a transgender woman. Bushnell could have been gender fluid, nonbinary, or something else. We don't know.

I respect every person's gender identity. I don't think a person's gender is something that should be investigated by other people. I believe that a person's gender is whatever that that person tells me their gender is. I respect whatever someone tells me that their name is.

In the self immolation video, Bushnell says "My name is Aaron Bushnell" at the start of the video.

I respect whatever people tell me that their name is. I don't try to prove that someone is something else.
