I don't want this to come off as offensive, because I am genuinely curious what people think.
I read that 40% of transgendered attempt suicide. Read somewhere else that 20% of homosexuals attempt suicide. I think the average for non-LGBT is 4-5% in regards to suicide attempts. 40% is an astronomical figure. Should we assume that all of that is because of bullying, not fitting into typical culture, etc etc, or should we look at it from a mental problem as well? Fwiw, 40% of people with schizophrenia attempt suicide as well. I think it's important to have the distinction made so we can help people as best that we can.
